I'm sure that's part of it compared to women especially. Although I've always been a bit of an outlier on top of that even going back to when I was a little kid. I've got a little (female) cousin now that's the same way, so we get to be the pair of family weirdos now. I think in a lot of ways it's more of being introvert types in a noisy extroverted family. I'm with you though if I'm in a bad mood I need to be doing something constructive, not hugging.
