Not really, I mainly say it as a joke. I don't actually say it in actual conversation. Also, you must jump to conclusions a lot because saying someone doesn't have a life just cause they said a word is pretty stupid if you ask me.
Just a thought, but how about givin people a chance before saying stupid things like that? I'm not trying to lecture you but I'm just saying, there are lots of really interesting people that have these sorts of interests.
