We've both cut back on booze for health and finances. We had none in our house and decided to make an exception for a night in with a friend.

I went to the store and bought, per my husband's request, a 6 pack of our friend's favorite domestic beer and a 6 pack of mixed IPAs with a couple specific brands. I'm not a fan of beer, especially IPAs, so I bought a 6 coolers for myself.

After a few hours and drinks later (me: 2, him: 3ish), I enter the kitchen and see him with a cooler, half-gone, in hand. I got mad and we argued.

His reasoning is that, as a couple that shares everything else, gettong mad at this was petty, and he thought I wouldn't mind because I can't drink all 6 in one night anyway. My reasoning is that I specifically bought that flavor and quantity for me to enjoy; I wanted the leftovers for tomorrow night. AITA?
