My younger cousin is staying with us for a couple of months, it's a really long story why this happened but that's for another time.
So he wears a uniform for school (he's in 9th grade) but he keeps forgetting to buy a second uniform shirt so he can rotate it and not wear the same dirty shirt two days in a row. Yesterday I asked him if he thought his shirt needed washing, and he grabed the shirt , smelled the back of it, and said "naaaaaah I think it's fine for tomorrow" I asked him to hand me the shirt and told him that he was smelling it in the wrong place, that he needed to check the arm pit of it to make sure and OMG I almost fainted...
That poor shirt needed to be washed BADLY, I just laughed and laughed at what my cousin considered still appropiate to wear, the smell knocked my socks off! I just took the shirt and put it in the washer with a load of whites.
