I always put on a mask before I go out but for some reason laundry day is an exception. I never remember on laundry day. I usually make it to the sidewalk with my full basket before I realize I'm unmasked, and then I have to decide if I should bring all my stuff back inside with me or if I should just run really fast up and down the stairs.
It's probably because my main mask is in the laundry basket, so I need to use one of my alternates - a white undershirt (I use my black undershirts for Big Outings, like Haymarket). The undershirt mask isn't an unusual situation, but it always starts by realizing my regular mask is still drying from a washing, and without this first domino in the chain I never remember that I forget.
