I grew up on butter and now I totally hate the taste of margarine. It's...gross. I don't really know how to describe it.
Also, do you guys get this feeling a few weeks into a new relationship that can be described as "incredibly uneasy", but only in the respect that you're afraid they're going to get bored with you/suddenly decide they can do better elsewhere/etc.? I don't really know how to describe it eloquently...I guess you could just call it feeling funny when a relationship becomes more than just feeling each other out.
