Ian owns 8 pairs of underwear. I know this because I bought him a 4 pack to make sure he’d accept a new style when I couldn’t find identical, larger underpants for him. (why, you ask? Remember the Polka Dot Diaper fiasco?)
Then I went back and had to hunt for the LAST pack they had in his size to complete his collection.
There are 7 days in a week. We have 2 hampers that get washed in rotation so the maximum time to clean laundry is 3 days. Subtract a pair for the change of everything in his school bag, and by my reasoning, there should always be at least 3 pairs of undies in Ian’s drawer. (1 in the bag, 1 on his tush, 3 in the hamper, 8 pairs total. 8-1-1-3=4, then figure on one less because he sometimes changes his clothes for no reason.)
But, every morning he goes to get dressed and then we hear… “BUT I DON’T HAVE ANY CLEAN UNDERWEAR!”
I think perhaps they’ve set up a secret guerilla base camp along with all the missing socks. They plan on recruiting the wash cloths next, so they can rely on force of numbers to overpower the larger items, like sweaters and bed sheets.
