As in there are some people you're naturally drawn to.
I find it interesting how humans click with some people and not others, and sometimes you hardly know a person and speak like you've known each other for years.
I was instantly drawn to my DH even before I spoke to him; not in an attractive way (though of course I did think he was very handsome) but in a "I need to get to know this person" way.
This doesn't have to be just about relationships but could also be about friendships
