I've come to the conclusion that everyone has some sort of expensive hobby, something they enjoy spending lots of money on.  For me, it's electronics like computers, cameras, and phones.  I regularly spend a good amount of money on new gadgets and toys while I simultaneously buy rotten fruit and used clothes to save a few bucks.  I wouldn't have been satisfied with a standard cell phone, so I spent a lot of money on a PDA.  I wasn't impressed with the standard options in my Dell laptop, so I spent lots of money to customize it. 

When I hear about someone spending tons of money on fancy clothes, I alert them to the fact that certain stores sell perfectly good clothes for much less money.  These less expensive clothes perform all the same functions as overpriced clothes, including covering nudity, keeping the body warm, and ... well that's about it.  Clothes don't have much more of a function than that.  But I suppose these people buy expensive clothes for more than just function.  And while I don't understand or agree with that, I guess I can accept it. 

Since everyone has an expensive habit, a lot of people will inevitably have different expensive habits.  I like electronics.  My friend likes camping equipment.  I knew a guy who liked guitars.  I know a lot of people who like cars.  I suppose some people like fine dining.  When I don't agree with someone's choice of expensive habit, I classify them as "stupid".  This is wrong.  I'll try to stop doing this.  Just because I don't share someone's interest in expensive habits doesn't mean mine or theirs is any more worthy.
