My clothes that I have hanging up in the closet...I arrange them by color, and I usually go by ROYGBIV (colors of the rainbow), and the whites/grays/blacks are on the outside of that spectrum. Lol.
When I'm counting my cash, I stack it so that the $1 bills are on top...followed by the $5's...$10's...etc. And the numbers on the bills go in chronological order. So if I have three $1 bills, the one that says "A4804..." would be on top...followed by the $1 bill that says "C1345..." followed by the $1 bill that says "F2458..." Then I do the same thing with the 5's...10's...20s.
Don't judge me.
