Sure, I chose mine because I was very sad and lonely. Does it show? I'm feeling lots better, but I've kind of gotten used to the little guy. And I'm still a lone. But not sad anymore like I was.
My avatar right now is just the crest for my university. I might change it shortly, but haven't the time because of exams.
By the way, I'm very proud to attend Trent University. The best primarily undergraduate university in Central Canada. Wooohooo Excalibur and Champlain College.
