One time I was working on a huge project with a lot of people and made a huge mistake. Another person from another company could have embarassed me, but instead he helped me out and covered for me. 
that's nice. i wish i had people like that to work with
I've never had that happen before either. It was a hostile environment and he certainly didn't have to help me, but he did. I've tried to be more like that since then.  
i wonder if he has a crush on you or wants something in return
Haha. I doubt that. He was halfway around the world. It was a long time ago and he never asked for anything. 
did it boost your confidence and faith in mankind?
Yes, it did. 
glad to hear it. i hope it's only grown since then
