Nah, I don’t think you’re petty. It’s just a matter of what’s important to you and personal tastes. I’d do all kinds of wild, extravagant things, but I’ve got a philanthropic plan up my sleeve (it involves giving homeless families a place to live while they learn to function in society and get independent, in case you cared) for when I get wealthy. . .
Still, there’s lots of obnoxious, shallow, fun stuff I’d do. But that’s one of the reasons I wouldn’t live in a McMansion. I wouldn’t want the neighbors rolling their eyes at me, and sniffing, and saying “My, she’s an. . .odd one. . .isn’t she?”
