This is so funny! At first I did, but over the years I have realized that everyone spends their money differently and all of my girlfriends and I are very different from each other, but very accepting of each others quirks. I hid truley who I was for a long time out of paranoia that my friends would think that I was a 'snot', but then I had an epiphany. Everyone can be snobby about something. Even if it is something totally different from what I would be snobby about. For example, my younger sister is a total snot about what brand of feed she buys her horse and spends plenty of money on what I would consider "icky" or "tacky" things, but everyone has different taste. It took me a long time to realize that my dearest friends truley love me for me, the insane, neurotic, fashion obsessed person that I am. I even lied for years not telling a soul that I had a housekeeper (I grew up extremely poor on the Mexican border of Arizona) because I felt like I had turned my back on how I was raised, only to find out just this year that my best friend has a house keeper too. Don't get too excited about this people, the cleaner only comes once every other week.
Anyway, sorry for the monologue. Bottom line is this: It is rude for people to ask how much money you spend, rude for them to care, YOU be YOu and everyone else can suck eggs.
