Am I rlly busted?

About a year ago we had a big family gathering and a lot of alcohol was left back we gave them away but kept a bottle that was already opened and my mom is insanely strict w my dad since she hates alcohol a lot and to make things worse during the year my dad got kidney stones and then strokes like 2 months later and had to quit all (fuckass man still drinks beer though) and the rum was hidden in MY room and we literally forgot about it... but I normally take from it and mix it in my drink but straight vodka just tastes so perfect and good, mixing it w other stuff is lame EXCEPT CRANBERRY JUICE OFC! Today My mom just brought it up and said she's gonna throw it away and I was joking saying "thats such a waste though, Ima just drink it" and like I was laughing w my sis coz like alcohol is a big NO for us and thats an obvious joke...anyways, I was heavily scolded and was about to get hit w a spoon even though I WAS JOKING. Sighs, This woman went into my room and took out the bottle to get rid of it and shouted to me saying "Why is it so little??' I somehow managed to make her believe that it was like that since they were drinking from it and she just slapped me and throw everything down the drain. I was just joking bro why so serious accept ur wrong gosh u won't even know if I took a lil sip, who would just sell themselves out like that ? girl, if i meant it as a joke then IT IS. Why are parents so stupid and always think theyre always correct in EVERY situation?? so fucking annoying.
