Ok so I have a friend and we completely have different hobbies. We also completely have different likes and dislikes. I wouldn't say we're the exact opposites. But there's times that I find her disagreeable, and agreeable. We only talk because we share our personal problems together and whenever she's down, upset or frustrated, I'd earnestly comfort her so she can feel better.

Honestly, she considers me as one of her best friends in her life and what upsets is that we both have different hobbies. We're completely engrossed to the things that makes us happy and I'm afraid that we're not gonna get along because of it. Any advice?
