is when they stop high fiving in scenes.
I (seriously) spend five minutes with every new group making sure they can all high-five each other successfully and casually.
This way you’ll never be in a scene where two people high-five and do it terribly, then it turns into spending the rest of the scene talking about how terrible you are at giving high-fives.
I’ve seen this too many times to count. It’s much easier to just high-five correctly and carry on with whatever you were doing.
Do it! Just five minutes will keep you from doing “that” scene.
(The same applies to picking each other up, making sure you can fly, stage slaps, and just generally touching each other, instead of warily looking at each other uncomfortably while you stand three feet apart.)
