All I know is that I had the same thing happen when friends of ours would have a little too much..I knew he was getting drunk so I simply moved away..if it continued I would have quietly asked him to stop if it made me uncomfortable..if he continued either he would leave if it was my place or I would leave if it was his place..
Actually had a husband and wife get out of control with both hubby and I one time and although hubby seemd to be enjoying it (even tho he was a witness) I wasn't ..I insisted we leave or at least for hubby take me home. The guy aplolgised and we did stay but we didn't see much of them after that if they were drinking. If they weren't drinking they were the nicest people you would want to be around. Some people just can't hold their liquor.
Snoozy..
