OK, I know the basics. Like you should consider the other person be a good person, agree with the important issues, feel the person meets your morals, etc. What I'm curious about is the other things. Shared interests, shared views, etc. Could you form a good relationship with a person who you only shared one similar interest with? (Ex: You both like the same movie.) If it's possible to have a relationship with only one or so things in common, what things are strong enough to be the only thing you share? As in, obviously you probably shouldn't form a relationship based on a shared love of pizza.
