Forgetting is a sign of forgetfulness

Oh well, if I’m you can’t remember what you need just shop in the snack cake, chips and soda isle. Four best effect, make sure to only go when you’re hungry

I maintain a Google Keep shopping list. Many similar apps available. When I see I need something, I put it on the list. I add to and update the list whenever it occurs to me. When I’m at the supermarket, I take out my phone and check the list.
