The delima of knowing or not knowing about my friends interests

I hate/love not knowing anything about a friend’s interest, like when a friend is completely passionate about _____, and I have no idea what _____ even means.

I hate it because it means I’m out of touch with part of my friend. And if it’s really a passion, then I’m out of touch with a huge part of my friend.

On the other hand, I love it because it means I have a vast opportunity to learn. If a friend’s really passionate about ______, then I’ll have an outstanding teacher.

So from both sides, I so want to not know anything about my friends’ interests and so want to know everything about them.

‘Tis a fantastic delima.
