i've invented a thing. everybody loves to greet friends with a fistbump but also everyone loves playing rock paper scissors.

from now on, the game is you go to fist bump and at the moment of contact you can choose to change from the fist to either paper or scissors or remain as you were. if you think the person has forgotten then you obviously default to paper. if you think that they think you have forgotten then you scissor them as they default to paper etc etc etc

thanks for listening
