What do you think is the limit of joking between friends?

The measure of joking is to know the bottom line of the other party, never touch it, always consider whether the other party cares about the joke, and then think about whether it is possible to make such a joke from the other party's position. Only mutual respect is a long-term friendship.

To put it simply, the measure is that he knows this is a joke, but he basically doesn't treat it as a joke, so I hate jokes and I don't like others to make fun of me.
