My 12 year old has turned into a full on tech nerd

And I don't know how it happened! I really think it happened gradually, overnight, and all of a sudden -- bam! It's right in front of my face. All of a sudden he's talking about html and green screens and how to create web pages. He wants to teach himself Html and even has a web page that he's started on his own, that he's stumbling along trying to work on himself. He carries around notebooks with movie ideas, and has ideas of doing a weekly webshow, kind of like Icarly.

This is a kid that up until last year was a huge sports nut. He played football, soccer, and loved everything sports related. Now he's into tech stuff and drama. Friends say it's because he's in Jr high now, and he's around a larger variety of friends, but it's so weird to me! He's my oldest, and it's so weird to watch him develop his own personality and likes.

I don't know HOW I'm going to handle it when he starts to get interested in girls!
