My mom goes through every aisle because she refuses to make grocery lists. She insists on trying to remember everything for some reason. Eventually she'd send me, without a list, and be all surprised pikachu face when I forgot stuff.
Now as an adult, I live by my grocery list. I've got a pad of paper on my fridge with the heading, "DON'T FUCKING FORGET" which my boyfriend and I add to as things run low.
