A little background. My grandma pretty much lives on Diet Coke. (Something like 60% of the human body is water. In my grandma I think that 60% is Diet Coke.) Anyway, she drinks it out of bottles because she can't finish a whole can at once. Usually she'll drink about half, then stick the other half in the fridge for later.
SO. She is mad at Brian because she is SURE that he took a drink out of her last Coke. Her opened, half drunk Diet Coke. She is convinced of this despite: A) the fact that Brian drinks soda from cans, not bottles, B) that Brian drinks a whole Coke when he has one, not a swig here and there, and C) that my mom, my dad, and Brian have all assured her that he did nothing of the sort. She will not be swayed.
Alright grandma, you found him out. Even though there's a fridge full of soda in the garage, Brian thought he'd just have a drink of the one you left open. And then lie to you about it. And have my parents lie to you about it. Because that's just the kind of guy he is.
Ah, life around here is never boring.
