A/N: Welp. This one's slightly depressing. That's where I'm leaving it.

Disclaimer: *looks at the stack of papers* There may be something in there claiming I own it, but I doubt it.

Donnie watched with a curious gaze as he watched his brothers laugh and run around. They certainly looked as if they were having fun...

Maybe he could join?

No, they seemed to be having plenty of fun without him; he didn't want to ruin it.

Just like always...

Most of the time, he didn't mind being left out of games with his brothers. If anything, it gave him a chance to read or play by himself.

On occasion-like now-he would sit off to the side and watch them play, wishing he could join in.

He just couldn't figure out how to ask.

Sure, sometimes the others would join in without asking, but he felt so weird doing something like that.

"You okay, Donnie?"

The genius pulled himself out of his thoughts at the sound of his oldest brother's voice and was mildly surprised to find Leo standing in front of him while Raph and Mikey looked at him from their spots on the floor.

"I'm fine."

It was amazing how easily the lie slipped off his tongue. He just didn't want to guilt them, though.

"Well...do you want to play with us?"

Donnie always liked it when the loneliness faded.

When he felt like he belonged.

A/N: Least it ended happy! Mostly. Fun fact: at like 11 o'clock last night, I thought of staying up a bit longer so I could post it today at midnight-ish. *looks at time* It's nearly 12 hours later.
