"having things in common" is what women say. it's their way of trying to say that the guy is relationship material because she enjoys spending time with him. that's how they say it, in their way. feminine men, in her orbit, pick up on womanisms like this because they think it will help them score points (they don't give a shit, they actually rather a man do his own thing, and be in his orbit but i digress). they can't just say "he's relationship material" because then you have retards like the guy in the picture who will get legitimately angry: "why aren't *i* relationship material but *he* is?" and things get awkward fast. for the "guy friends" (stuck in the friendzone) they have to be incredibly delicate and tell him things like "oh you're such a nice guy, i'm sure you'll meet someone" - so she can continue to just use him for whatever she wants. "things in common" doesn't apply to guys. i've had several happy relationships with women that were all way to the left to me, not interested in any of my hobbies at the beginning. over a long enough period, if you know what you're doing, she will become interested in the things you're interested in. women are often not even that interested in the thing itself but the community (drama/status games) around it. that's how you introduce a woman to anything. she will gradually attach to the thing after enough time. sometimes you can "luck out" where she's already interested in things you like. but it's always a man who kindled that interest. whether it's her dad, her brother, or her ex. even when it comes to things like sex. women are useless. if she asks you to do this or that specific thing or shows off some "move" to you unprompted, it's something she picked up from another guy.
