#8. Laughter requires precise timing
In conversations, people time their laughter to occur very precisely at the ends of sentences. Even people speaking in sign language do this – despite the fact that they could laugh throughout their “silent” conversation if they wished to.
I’m intrigued by how comedians co-ordinate the responses to their routines from the stage. It’s also difficult to learn to have the confidence to leave a pause for the audience to laugh, and to cope if they don’t. Comedians are very sensitive to the way that laughter can grow and fade in a room, and leaving a space for laughter to happen at all is a real skill. Source
