The most obscene thing I probably do with my food, though, is put ketchup on pasta.
I don't think that's weird at all (very, very common back home), I do it for all kinds of pasta - but every American I've ever met have gone bug-eyed and looked at me like, "OMFGSODISGUSTING!" It makes my current boyfriend sick to watch/smell, so I don't eat pasta around him. I think I traumatized him when I put ketchup on mac & cheese.

As similar as my home country is to America when it comes to lifestyle, economy, progress, whatever, there are some obvious glaring differences, haha!
