I don't exactly consider myself a pro, but I'm not a fan of referring to photography as just my "hobby".
Nowadays I have to talk very much about my photography because nearly all my friends know what I'm doing and I put very much emphasis on the fact that it is only a hobby for me. A damn expensive one, that's right, but I have the feeling people appreciate more what I do when they know I do it not because I have to but because I want to, and that in my spare time. Also grants me the possibility to turn down requests for portrait shoots with people I don't really want to waste time on. I don't want to see it as work, and I don't want to do free portrait shoots of people that are clearly not photogenic.
So, I'm no pro obviously but I would label myself somewhere between very ambitious hobby photographer and semi-pro
