I was in a dinner the other day and they unfortunately sat me in a booth next to a college student who was whining about her life and a particular professor at school.  She turned in 7/10 of a project and felt that would be enough.  She was all put out when the professor gave her an incomplete.  Her attitude was, how dare they, I did a lot of work on that.  How about actually doing the complete project next time?  It’s easy to be incomplete in life, so do the whole thing.
