I can relate to having it beaten out of you. There were definitely many years after school where I'd learnt to suppress and hide my geeky interests. There's no way, for example, I would have been visibly excited when a train went past. More recently I've stopped suppressing it, though. Now as a 36 year old man I will run to be able to see a train go past if I want to. It helps that I now have friends and a girlfriend who are just like me. It turns out if you find the right people these are attractive qualities.
