I think you’ll be put at ease when you get to meet him and see how your kids interact with him.

She probably knows you would make fun of his height, so that’s the first things she mentioned. She’s probably not physically attracted to him and doesn’t want you to laugh at him ( on the inside, of course)

I hope he is really a decent dude. Table manners are cool. Eating your vegetables are cool. I probably wouldn’t like chicken every day. But I hope he is teaching these things kindly.
