I made a post about mockery a while ago. https://sanerthanlasagna.wordpress.com/2016/01/11/mockery
But I neglected one of the most important and beautiful aspects of mockery: Mockery, if done right, is a fantastic way to demonstrate your closeness. If you are afraid of teasing me, it shows me that you aren’t certain of our mutual affection. If your love of me is so effusive that I am certain that your insults come from a place of love, it makes salient our love. Mockery can highlight just how secure our bond is.
