Do you have kids?
Kids who don’t want to do something “boring” like attend campaign events act like that.
I remember when my brothers and I had to go with the parents to visit the great aunts/uncles. There wasn’t a toy, pet or person under 40 except for us. It was torture.
I have two children, now in their 30’s and they always gave their parents hugs and kisses. Maybe other peoples’ children find their parents are just like Creepy Cruz.
