My favorite thing in the entire world would be heart to heart conversations
I truly believe it brings others close together, you feel so vulnerable and there's lots and lots of tears, but it always pushes you one more level of comfortability with that person no matter how comfortable you were with them before it. you tell each other things you've never thought you'd hear or say, there's no sugar coating.. It's so scary to have, but it's necessary to have if you want to be closer with someone. I've only had it with like two or three people, so it's very rare for me.
