There's the rub, I straight up can't trust my memory like that, I might remember needing to do something but then forget that I already did it.

With that milk example, I'll remember that I need more milk, get the milk, go home, open the fridge, see milk already there, remember that I already got more milk a couple days ago, put new-new milk next to old-new milk, and legit fucking do it again a couple days from now leaving me with three jugs of milk. Memory is borked I guess.

Fun fact: I have so, so much tooth floss and white rice rn due to this fun phenomenon
