A Short Conversation

Hey guys.
Being an actor, I have multiple "characters" that take the shape of my different characteristics. Basically, they're just exaggerations one of my characteristics and they get all melodramatic. It's pretty fun, and generally cheers me up.
When I'm distressed, or annoyed, or sad, or something, I'll write about it.
Generally, I write conversations between two of my characters. This was between the depressed, pessimistic side of me, and the one who tries to help and cheer people up. Both have their flaws, but they end up helping each other.
...Ah!! I wrote only dialog!! Very well, I'll add some actions in there.
Uhm... they don't have names... so I'll call them... uhm.... Mara (bitter) is the pessimist, and Alexis (helper, or defender) is the one who helps people. Oh, there are two other dudes in here that are based off two of my friends....... I changed their names (or only insinuated they existed) for both their sake and mine. *smile*

A petite girl sat on a wooden bench in the park, her head down and her black hair falling around her shoulders and face. The park was full of trees, all shedding their colourful leaves. There were no people; it was too chilly and the sun was smothered in gray clouds. She didn't mind the cold, or the clouds. In fact, she enjoyed them. She stared down at the leaves in between her feet and thought about what had happened that day. Alexis, a cute girl with fiery red hair, walked down the sidewalk, looking for the black haired girl, Mara. She saw her and her brown eyes lit up. She jogged to the bench and sat next to her.
"Hey sis. Can you come back home? Please?"
"No."
"Come on... I'm sure this won't happen again. Please don't let it get you down."
Mara turned to look at Alexis. The tears in her dark purple eyes spilled over and ran down her cheek. "I know this won't happen again. They won't ask me again."
"At least they asked," said Alexis, looking down at her dirty shoes.
"Yeah..."
"They love you."
"And I'm letting them down!" Mara yelled. She put her head down again and the tears fell to the leaves below.
"It's not your fault."
"It wouldn't have happened if I didn't choose to dance."
"If you didn't dance, you'd be miserable."
"So what? Friends first."
"You wouldn't be able to help your friends out if you were depressed." Alexis looked sternly at her sister.
"Yeah... I also wouldn't feel like an idiot..." Mara mumbled.
"You're not an idiot."
"Yes I am."
"You're just unwise."
"AKA idiot." Mara was in a foul mood, and not ready to agree with anyone.
"No."
"Yes."
"No, you're not."
"Says who?"
Alexis gave her a knowing look. She knew who cared. Mara glanced at Alexis and quickly looked down again.
"Fine... I'm not an idiot."
"See? Told ya so."
"Shut up." Mara said, quietly. "I still do stupid stuff."
"That's because you're human, smartypants."
"So? I should be perfect."
Alexis sighed. Why was her sister such a perfectionist, she wondered. "But you're not!"
"Exactly."
"You can't be perfect!"
"I know."
"So why try?"
"Doesn't God want us to be perfect?" Mara looked up at the dim gray clouds.
"Ah, true." Alexis leaned her back against the bench.
"Also, if I don't try, I feel like a failure." Mara looked back down at the ground.
"Bah. You're not a failure."
"I let my friends down. I let my teachers down. I let... my family down." The last part of her sentence was so quiet that Alexis hardly caught it.
"There are people who you don't let down."
"No there aren't."
"Yes, there are."
"Who?"
Alexis was silent.
"See? I've let everyone down in one way or another."
"But you also help people."
"Then I let them down."
Alexis sighed. This girl just wouldn't give up. "Not necessarily."
"Yes, necessarily."
"You haven't let Jesse down yet."
"Just watch, I will. I did."
"Yeah, then you helped him."
"No I didn't."
"Yes you did."
"Yeah, and it killed part of me." A leaf from a nearby tree slowly drifted to the end of the bench. Mara watched it as she said this.
"Trust."
Mara looked at her sister, confused. "What does that have to do anything with this?"
"Trust! What holds friendships together?" Alexis wondered why she said this, too.
"What if I can't."
"You can."
"No I can't." Mara looked down again.
"If you fall, there will be people there to catch you."
"There haven't been."
Alexis got up and walked to face her sister. "Look at me."
Mara looked up and saw Alexis with her hand raised.
SMACK
Mara looked down, her eyes wide, her cheek stinging from the blow and the cold.
"Yes there have." Alexis put her hand down and glared at her sister.
"Fine. There have."
"I love you." Alexis offered her hand to help her sister off the bench.
"... I love you, too." Mara took Alexis' hand and they walked back home, together.

My characters seem to be as ADD as I am! Their conversations always seem to jump back and forth... ah well. They also don't resemble one another very much... black hair, red hair... purple eyes, brown eyes... there are no such thing as purple eyes! Oh well!!
I'm not a very good writer, I apologize. I suppose I can justify myself a little by repeating the fact that this was just dialog, and I had to add some actions so you wouldn't get confused about the speaker...
I may introduce you to my other 'characters' at a later date. In fact, I probably will. Even though, I always say I'll post something I never really end up doing it... But whatever.
I did try to post something more about peace, but I suppose I'll just have to wait until I get inspired again...
Uh... yeah that's it. Enjoy!

Love, Sarah (and Mara, and Alexis)
