Relationships and Sociology

I wanted to have a thread that could generate positive energy, so I want to ask you all: what are your favorite non-sexual gestures of affection?

For example, I still recall feeling warm when and ex would pinch my nose. He still does it with his kid and it's simply heartwarming. It's just how he shows love.

I like squishing the faces of the people I love. Adorable faces in funny shapes are super cute.
