I think a good idea would be talking about yourself more and them less. Instead of saying "Yeah, for you I bet it feels like you saw this life changing movie and it sucks not being able to share that." you could say "Yeah, I know what you're talking about, I'm the same with Japanese Literature, I read some wonderful book and then I have no one to share that experience with" (or whatever you're interested in). This shows that you can emphatize with the feeling but don't share the interest. Maybe?
