When my oldest son was going to be a teenager, I had his room completely redecorated the way he wanted it (this is back when computers were big lumpy boxes & there was no such thing as a flat screen tv).
I had a futon in there to be a sofa/bed if friends stayed over, a computer, a tv, playstation etc..
It had EVERYTHING, even a cold drinks fridge.
I had been told all about how teens disappear into their rooms & all you'll hear for a few years is a grunt if you ask them a question.
I was looking forward to it to be honest.
It never happened. Not even the grunting thing.
He was a perfectly civil young man who wanted to talk to me.
I even dropped a few unsubtle hints but he just laughed at me & thought it was funny.
He still used the living room as his main living room, constantly bringing things (teen equivalent of toys) in there instead of using his bachelor pad style bedroom & when his mates were round so did they.
I got my living room back when he left home for uni, then lost it again when I had my youngest.
He'll be at home for years yet so I'm not optimistic I'll get it back until he goes to uni.
This time, instead of creating a brilliant space for my teen, I'm creating a brilliant space for me in my bedroom.
I plan to hide in it & reply with a grunt if disturbed.
I should have done it the first time round.
