If I had $1,000 just for me...
Well this is a tough one. I would probably spend most of it new clothes. I would mostly buy work clothes for my full time job. I need to update my look at work at bit, and this would give me that opportunity.
I would probably also pick up a few items just for fun. Maybe a new pair of jeans and some fun shirts. I'm not overly trendy, but I like having clothes that look good and make me feel like a normal person. Sometimes I forget what that is like. I so rarely get treated like a girl I get bogged down by how much that feeling hurts. Dressing cute helps me overcome some of that.
If there was anything left, I would buy Beaker, Batty and Abby a bigger cage. Plus I'd through in some new toys for good measure for all the fids.
