Use to tell me when working,"1 boy is a boy,2 boys are 1/2 a boy and 3 boys are no boy at all". Working grandson(13) and one of his classmates putting metal on roof of a building with 4/12 pitch. Scooting their butts across and up and down instead of standing and leaning forward. I can take 1 and get along fine. Put the 2nd in the equation and progress really slows. Just bite my tongue and point and say,"do this". I put the other side on by myself. Muscles too sore to finish this side. When you do something you are not used to it sure does make you take note.
