5. Don’t put your drink down.
This is a really important one. For the sake of staying alive, I always assume everyone at a party has a certain amount of roofalin on their person. My drink never fully leaves my line of vision. I probably look like a paranoid crack head, scoping out all the people that get close to my beverage, but safety first!
Don’t bring your own red wine and then spill said wine on the host’s expensive pillows. It’ll make things awkward for everyone… just… Trust me.
