Yes, so normally our CMPT140 class has three TAs who each take a four-hour evening shift in the computer lab each week, helping students with their programming projects. But one of my TAs is sick this week, so I decided to fill in for her; I have a ton of statistics marking to do, anyway. It certainly makes for a long day at work, though, staying until 10pm! Just the other day in office hours one of my math students made this offhand comment about how her professors who are single seemed to have more time to spend with students. Ha, that's just 'cause we have no life outside work! :) Then she added, "but some of them seem more unhappy, too". awww....
