These people 1) wait until the last minute to print something out, then 2) freak out because the printer doesn't work... and 3) beg you to solve their problem.
I would consider myself to be a mix of both. I always feel really bad when I call my mom and ask her to send me things that I left at home, and I'm surprised that she still continues to do it whenever I ask. I'm really grateful for her patience.
I'm working on it... forgetfulness is a trait that can be fixed, if you have the right tools. (That's part of the reason why I love to make lists!)
