I'm not very girly so was happy when I had 2 boys. I loved it, even the Thomas the Tank Engine and general train obsessions and indulged it all. Then they got to the age where they didn't want to go out much with me in the holidays any more to do kid type activities and gradually became much more interested in chatting/watching football or going to the match with their dad, or spending all their time on the xbox or PC with their mates playing more grown up games. I used to like doing things like wii sports etc with them when younger, or playing box games and that, but then they got obsessed with Minecraft and Fortnite and then other games for older teens/adults. They stopped reading and I missed our conversations about books (we had read the whole of Harry Potter together when they were about 11 and I took them on my own to Harry Potter Studios one Christmas which we all loved. DH wasn't interested in HP at all so didn't get involved in the reading or studios trip).
For a while they did sitll want to watch some TV shows with us that we also liked (loved watching Breaking Bad for a second time, with them), but then they gradually just wanted to spend time doing their own thing or with mates.
I mean, that's all normal and healthy and fine, but the time that they DO then spend with you it would be nice if wasn't mostly football talk. Their dad loves it, obviously, but I often feel a bit left out. I guess it's the mid-late teen stages that the girl/boy differences become more apparent. I watch other mums with late teen daughters enjoy things like watching Strictly with them, or other telly pap, or go to gigs with them, or shopping trips or enjoy doing their rooms up with them. Or they like having the fashion or makeup advice from their daughters. And chats about boys or just life generally. Whereas my boys can't stand the likes of Strictly, they like different music now like rap, they aren't interested in fashion or shopping, their rooms are a tip and they don't care, and they don't do deep chitchat about their life - just facts. They have turned into your average bloke!
I'm often reminded how my dad must have felt when my sister and I were teenagers. When we were pottering around 10 different gift shops on holiday looking for the perfect bracelet or ring, he used to take himself up the street and have an explore - in hindsight he was probably bored shitless at the thought of yet another gift shop but he never complained, just took himself off quietly for an explore up the street till we were finished.
