Nope. You're not weird at all, Liam.
When I was your age, I spent the vast majority of my time in my room alone, either reading, listening to music or watching videos (back in the old days when they HAD videos) I never watched TV much at all.
I am now 49 years old and even now, I NEVER watch TV. Most of it is rubbish anyway - just a load of reality TV nonsense or depressing drama programmes. I must admit that I do like EastEnders, Corrie and Neighbours (yes....sad I know
) but I only watch them online on the channel websites. Other than those three shows, I find stuff on Youtube to watch, or play a lot of games on my tablet. My TV just sits collecting dust at the moment!
My family are like yours. My parents and sister just love their TV and watch everything under the sun - Strictly (which I LOATHE), all the police drama shows/historical dramas and get really enthusiastic about it all. I don't get it at all, but hey, everyone is different.
Don't worry at all. We all like doing our own thing and if you are not a big TV fan, it is no big deal. You like what you like and that is perfectly ok!
