DH and I are having a disagreement about ice cream.
Person A bought a 2 pack of gu desserts. They ate theirs and then person B offered to swap their dessert for a tub of ice cream that was already in the freezer and "belonged" to person A.
Person B then ate the gu dessert, having forgotten about the deal. They replaced the dessert the next day but as they only come in a two pack, they are the second dessert.
Who's is the ice cream now?
Person B thinks that their second dessert is irrelevant to the situation.
Needless to say, this is lighthearted!!
