I just had a rather terse exchange with someone about those people on Facebook who have so little in their lives that those 3 copy band gigs per month define who they are and they post pictures of their drums as a profile pick JUST so people hear them say "Look!! I am in the club! I play drums!! See???"
It's just a part time job.... I don't post a picture of the car I use to deliver auto parts 10 hours a week....
yeah... I do see your point. But in all fairness, there is a perceived difference in cool factor, even though they're both part time jobs.
And although it's true that most people don't identify themselves by their jobs, they DO tend to identify themselves by their hobbies. Music is unique in the fact that it can be both.
