To avoid being boring you should focus a conversation also on the other person. Try talking about things he may know, and make a joke when necessary. You should consider what they like and what keeps them entertained.
*Deep Andy Sixx voice* Ahhhhhhhhh!!!! Oh hi Zach That is so not an answer, but that's what you gotta do. Try to be funny, crazy, weird, and.. that's really all. Just be yourself. If you're a very boring guy; just saying.. try at least to be not boring, and like the things I mentioned to you. If anything gets awkward; at least you tried, and you would just have to find some people that like to have fun and who are so funny and crazy(;
Sometimes you have to have chemistry not to bore someone<3 If you guys talk a lot, it's easy to run out of things to say but as long as you're talking, that should be fine? Plan special things you guys can do or talk about your dreams for the future:) questions about random likes and dislikes or the question game always helps me:)
