Piling on to your hobbies beef, it also implies that you're going to have hobbies that aren't inherently gendered. I am not trying to be sexist at all or prescriptive about which hobbies people should engage in, I'm just going to issue an observation that all of my husband's video gaming friends are men, and 80% of the people in my gardening groups are women. He's also into music, which is probably more mixed, but everyone I talk to about books also ends up being women.... But that could also just be the genre.
