A Walking Travesty

Alex sighed, sitting in the usual back seat of his classroom. No one ever sat next to him - Not because they were scared, or he was genuinely horrible, but he was really closed up and refused to speak to anyone about anything. But he had his reasons. Alex had been in many relationships, all of them ending badly. His most recent relationship of 2 years had just fallen apart, after he found out his girlfriend was cheating on him. He ran a hand through his hair, hoping that no one would sit by him - Not that they usually did.
"Hey, I'm Jack."
Alex looked up, his eyes meeting with a pair of dark brown eyes, similar to his own. The only difference was the sparkle in Alex's eyes, which had faded out a few months ago, after a tough break up, that he still hadn't forgot. Alex bit his lip and nodded. "Alex." He said, his voice barely above a whisper. He felt physically sick - He didn't like the thought of friends, girlfriends, boyfriends... He didn't know who he could trust anymore. It was now at a point where he couldn't have a conversation without feeling ill. He'd never had anyone he could trust in his whole life. That wasn't going to change. He looked over at Jack, who was grinning widely. He couldn't help but smile back.
Alex felt Jack's eyes on him, looking up, realising Jack had been holding his hand out for a while now.
"Oh, sorry." He whispered, taking Jack's hand and shaking it, giving him a weak smile before looking back down.
"That's fine." Alex almost wanted to scream as he saw the other boys cheery smile. He used to be like that. What happened? Why couldn't he be like that? Why did there always seem to be something that weighed him down, something that made him sad, unable to smile. He put his head against the desk, surprised when he felt a hand on his back. He looked up, a smiling face staring back at him.
"Please don't be sad. There's always something worth being happy about." He smiled as he heard the words escape Jack's lips.
"That's so cheesy and cliché. Tell me then Jack, what's so worth being happy about? What's so worth living for?" He asked, speaking up a little, though his voice was still quiet and muffled.
"Lots of things. Family. Friends. Love. Life only gets better. It's an amazing thing, don't go wasting it."
Alex laughed. "I was right, you are /so/ cheesy and cliché." He rolled his eyes, though he was smiling. "You're just a typical teenage boy who thinks love makes everything better."
"You think?" Jack smirked. "You obviously don't know me very well."
Alex smiled. "I have only just met you." He whispered, remembering that fact and biting his lip. He hadn't told Jack anything secretive, it was fine... It was fine. Absolutely.
---------------------------------------------------------------------------
Another day. Another lifetime, as it felt. It started off okay, until it got to lunchtime. Alex was sitting in the library, alone, as usual, when he heard a voice. That voice. The voice of the cheesy, cliché boy, he had met the day before. Jack. Alex couldn't help but smile a little.
"What do you want?" He asked shyly, not looking up.
"Nothing. I just like to see you smile. You don't do it often enough you know."
Alex continued to stare down at the table, but even he could see Jack grinning widely. This boy never seemed to cry, he never had a bad day. To Alex, it was mad. Just smiling was hard for him, he couldn't imagine doing it constantly.
Alex bit his lip.
"Yeah, I guess." He mumbled, still not looking up, now digging his nails into his hands, biting down on his lip.
"What do you mean /you guess/?"
That stupid smile. There it was again. Alex could /feel/ it. He sighed.
"I don't know. I don't know." He said, raising his voice slightly. "I barely know you and you're asking me why I don't smile! That's like asking me my whole life! I don't know, okay?!" He said, getting a little scared now, a little worried. He covered it up with anger, almost to shield himself. He hated people asking questions, and hated answering them even more.
"J-Just... I hate you, leave me alone!"
He stood up, tears forming in his eyes. He looked up at Jack. He looked hurt, a hurt that Alex knew only he could've caused.
"I didn't say anything! I wasn't asking your life I was just trying to be your friend! Do you ever wonder why you're alone? Because you don't /let/ people befriend you."
Alex fell into his seat at Jack's harsh words, curling up. "Y-You don't know anything... Y-You don't know me." He whispered.
"Sorry."
That was the last Alex heard. Jack must've gone, wanting to get away, quickly. Alex didn't blame him. He was a freak.
