The Army has a saying. Actually, the Army has lots of sayings, but a really common one is, “shut up and color.” I think this is a throwback to kindergarten when teachers would implore kids to focus on their artwork in a vain attempt to gain a few minutes of quiet.
In the Army it usually means, “I understand that you don’t like the order you were just given. Go do it anyway.” Or, it is a self-imposed resignation as in “I was going to push back on this thing because it doesn’t make sense but the guy in charge was really hot about it. I decided to just shut up and color.”
Either way there seems to be a lot of crayon work going on.
