For as long as I could remember, our sibling & I would do rock-paper-scissors to determine who has to do what.
This is how it was when it came to doing our chores & things like that; Like if it was our turn to change the air filter for the Heating, Ventilation & A/C system, I’d challenge him to rock-paper-scissors & the loser would have to take on the chores of the other.
We’ve regularly been close while growing up & eventually all of us both even decided to become Heating, Ventilation & A/C servicemans. Oftentimes, all of us even get the major commercial jobs where all of us work together. The two of us work pretty well together & it’s no surprise that things are often assigned to us that way. I guess you could say all of us developed a bit of a reputation at the Heating, Ventilation & A/C shop. Everybody knows how all of us settle our disputes, with the rock-paper-scissors. The funny thing is that anybody else who challenges us can never beat us. The two of us are so focused on it that all of us regularly guess which to throw down. With each other though, all of us guess how to trick each other so it remains seriously competitive. Sometimes when all of us are on separate work assignments, all of us might do rock-paper-scissors to see who gets the better work assignment. It’s just a general rule with us, when challenged, you can not turn down that challenge. The two of us are so ridiculous with it all, our wives are driven mad by it, but even they have become great friends. Our wives enjoy us though no matter how ridiculous us siblings can get, & they are the best.
