They should take disagreements outside, how rude. I have seperated them, like take the woman out back for a chat.

There is not a better thing to do. Pretend like it isn’t happening and then slowly move away is the best response.

If this happens in my home then whatever I choose to do is appropriate, that’s my turf!
I’d very quickly intervene reminding them there’s a time & a place for that & this ain’t it.

MYOB.

Hold up score cards.

I might interrupt and say something like, “Ya know, there’s no one on the back porch right now if you’d like some privacy.”

Since they are being rude to argue in front of others, I feel it is OK to be rude back at them. I have been known to interrupt the disagreement to tell them You’re acting like 2 year olds. I tell the wife to go stand in one corner of the room & instruct the husband to go to the opposite corner. Then I tell them that they can’t come out until BOTH of them can once again act like an adult. Most of the guests break out in laughter & it usually seems to defuse the situation. I’ve also told a few to take it outside because NOBODY wanted to hear it!!!

I’d prefer to NOT get involved, but some people leave you NO other alternative!!!

I get out the boxing gloves for them. Solves most disagreements and you get a great workout in too.

Zone out
