If the shopping list is a physical note, it looks like this:

    Milk (1l)
    Bread
    Actually, ignore what we discussed, I'm writing this here because I was ashamed to tell you in person, but I'm thinking of breaking up with you, and only want you to leave quietly and not contact me again
    

Do you think the person reading that would just ignore it and come back home with milk and bread and think nothing of the other part?
