I've been working with R on the typical social niceties. You know, like saying "Yes, please" and "No, thank you" and, particularly, "Excuse me" after certain bodily noises. He's generally really good at remembering, but there are always some slip-ups here and there, of course. No big deal.
I've also been working with R (and A!) on saying "Amen" after grace at meals. I'm always the grace-sayer, so I'd at least like that "Amen" at the end as some acknowledgment that the other two people at the table listened.
Last night during dinner, a noise came from R's butt. I waited a few seconds for the obligatory "Excuse me," but when it didn't come, I reminded R, "What do you say?"
He looked at me questioningly and said, "Amen?"
Unfortunately, A and I laughed so hard that I think we may have sanctioned an unfortunate family tradition.
