Why?

Why do I find it so hard to spend money on myself? Yes I purchase clothes on a regular basis, but I'm a teacher, my clothes often get stained or ruined or shrink because I wash them so often. Plus, clothes are a necessity. Anyways, I made a purchase. This was a want, not a need. A purchase that I'd normally NEVER spend that kind of money on one. But, for once, I feel I deserve it and that's how I'm justifying it. What is it?... You'll have to wait until it arrives...
