What's wrong with smelling nice and having white teeth?
I wear cologne, and have had my teeth whitened professionally, when you have a job or have to interact with people these sort of things matter.
Some people just are butthurt that they can't seem to have a "sense" in some of that stuff. Plenty doesn't, most I'd say, not a biggie, but these are the ones who usualy try to make fun off it. I used to think that expensive clothes are a waste of money in general, but I did not have money to buy them at that time
When I finally started, I started to understand whay are they expensive, and very often it's not about the "brand", some people just MAKE quality products and it feels, and it looks. Apple products may be overpriced, but they are at the top of the quality, and I don't have a Mac, but I can easily acknowledge that.
