When choosing a user name I was looking for something to do with my mental state. Crazy. I came up with all kinds of variations. All of which were used. Then it came to me that I am not crazy all of the time, I go through moods like a hooker goes through condoms. I change moods easily with my surrondings and the moods of those around me. So change4adollar is kind of like "will change myself/mood for one dollar" or something along those lines.
As far as my icon, Izzy was one of the most important things in my life then (as now). I had only had her for a little over 1 month. I thought that she was the most beautiful creature in the world, I still do. It was the obvious choice in my mind. It was the essence of the first major goal in life that I accomplished: Get a dog. That may sound silly, but it was a HUGE thing for me. I love that little shit to pieces.
I realize some usernames are obivious, such as your actual name. For those types, why did you chose to go with that over anything else?
