history: Once I was working on a big project with a bunch of people and made a mistake. One of the other people working on the project covered for me even though they didn't need to.  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_comma_ but instead he helped me out and covered for me. 
current: that's nice. i wish i had people like that to work with
next: 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.
