Over the last few weeks my DH has picked up a habit of saying "right?" at the end of sentences, eg "That house is up for sale, right?" sometimes in a questioning way but also as affirmation on something he already knows.
"The table for dinner is at 8, right?"
"We're flying out on the 18th, right?"
It is making me stabby. AIBU to stamp my feet every time he says it to try and get him to stop? It sounds like a vague Americanism, like starting sentences with "so".
