Sweetie has a weird neurosis regarding his navel. He does not like people to touch it. Ever. Even the cat accidentally walking across the navel is a very bad thing indeed. And he'd prefer not to see other people touch their navels, either.
Hey, we all have our weird things, this just happens to be his.
The thing is, I've been a little obsessed with my belly button as of late. When you are pregnant your belly button frequently "pops" out, from an innie to an outie, as the uterus grows. And I think we're starting to move that direction. So I'm constantly playing with my belly button, trying to decide if it has shrunk or not.
And, from what I gather, if you are someone who does not like to have your belly button touched and you live with someone who is obsessively fondling their belly button it is not the most fun situation in the world to be in.
