history: It's easy to get irritated when you're working on a project and your teammates don't pull their weight -- but then *you're* the one who somehow suffers the consequences! I was recently working on a project where unfortunately_comma_ my teammate really didn't pull their weight.
current: That is the worst!! I know that you must have been very frustrated with your teammate.
next: Yep. Especially when you feel that you get dinged for the overall project. And at the same time, you don't want to complain about it, because it makes *you* look bad!
