My friends only love to go to pubs. Nothing else. What should I do ?

Find some new freinds you are not abnormal I used to hate going to same place constantly it gets monotonous!!! I understand what you mean try to hang out with another crowd or a few people that are into the things that you are into or you will get stuck going to the pub again. You seem like a smart person use your brain and do something you like to do!!!
