I don't watch TV
I stopped watching TV in 1990. Because of this I cannot watch TV. In my last relationship my partner didn't watch TV either - a happy accident. Sometimes I totally forget other people watch TV. This seems absolutely dreadful to me.
EDIT: So, in the context of dating - not watching TV seems to be a deal breaker. That and not wanting to sleep with animals in my bed.
EDIT 2: Okay, here's the truth. Someone invited me to watch TV. I don't know how to say no.
