Some of my yuppie neighbors look at me like I shouldn't live in neighborhood, what gives?

I am single and live in a very nice newer development. In fact, I was one of the first people to buy a home here. All the yuppies stated moving in and treat me like an outcast. I kinda laugh, because a lot of them had to sell their homes 1-2 years after moving in cause they couldnt afford them. I paid mine of in cash at age 39. Maybe its the fact I don't dress like a yuppie and drive an older piockup and harley and have long hair? Anyway, should I even care?
