Uggghhhhh. Jackson keeps messing with things when he's up before me. I don't know what else to do to tell him to leave things alone that aren't his. This is the second time he's dumped bottles of water from god knows where into my kureg. And he lied about it. I know he thought he was just helping me fill it... but I have no idea where those bottles came from🤢 I've asked him time and time again to leave water bottles aloooooone!
