Donnie liked to hang out with you, that was definitive; you listened to him extremely well, even when he rambled on and on about one of his inventions or the one hundred digits of pi. He even taught you the Pi song, to which you did not remember- but you listened! Which was more than he could say for his family.

Even now, when he was tinkering with some tech, you were with him. Though, you were the one that was yapping away, and he gladly listened. He appreciated the background noise, it helped him concentrate.

Up until he heard the word "friend" leave your mouth did his hands pause in what they were doing. His dark eyes glance at you, but he continues to work after a moment.

"Friend, you say?" The mutant turtle asked casually, a mere inquiry. It wasn't because he felt a bit jelly. No, of course not. He liked your company, of course. But that was all. That was it. He was just curious about this friend you have. After all, he's never heard this information.
