I have a granddaughter that can have this stand-offish attitude. You want to talk to her or take her picture and you will get arms crossed nasty looks and growling.......
Then I have a niece just a tad older that is such a joy, well I can't have her so........lol
My DMIL got shingles across her forehead, and someone else got them around where their wasteband is.....it is not fun and if there is a chance of not getting it I would get the shot.
Good handling of your problem.
Loved the story about the grands. I remember days just like that.
After seeing DH's misery with facial shingles, I had the vaccination.
Funny about the grandkids.
