Is AUTHOR wrong in the post ? POST : People are saying I overreacted but I thought I handled it well. Today at a family gathering I got up and left my drink at the table. When I got back I took a big sip and realized it contained alcohol. 
My cousins were filming me for my reaction and I laughed with them but later I messaged the one who put the beer in my drink and told her not to do it again. She knows I’m 100% against drinking because I’ve seen how our alcoholic family members have ruined relationships with their families that way. She then half assed apologized but told me it wasn’t that deep.
My other cousins are now telling me it was just a joke and im taking it too hard. AITA for being (not even mad) annoyed over this? 
They say it’s just a bit of beer but I say it’s the principle of it.
