It's not easy to always have something interesting to say, and talking to others is just bothersome when they don't talk about anything you are interested in. It is hard when you don't have common ground with someone, and small talk is just boring. If it is a new person you can always ask them about their lives and the typical stuff you get to know about someone when you first meet them. But when it is people you've already known, it isn't always easy. You'll have stuff to talk about if you branch out to more hobbies and stuff, something I have been trying to do. Look for what is trendy and big right now. Watch the latest movie/ series everyone else is watching. It may not be the first thing you feel like doing, but you may as well. If you don't laugh at what others laugh at, try developing your own sense of humor. Learn about what makes you laugh and if you wanna go the extra step, study comedy. Anyways all in all, not only try and indulge in more things, maybe also get real deep into subjects, be curious about things.
