Really? You guys think this behavior is odd?
I was very snuggly with my dad until my mid-20s, when he died. I wouldn’t sit in his lap and read a book or anything, but if I came home from work and he was sitting in his recliner, I’d often sit briefly on his lap, give him a kiss on the cheek and a hug, then get up. In the evenings, if we were in the living room watching a movie and we happened to be next to each other on the floor, I’d often put my head on a pillow in his lap or put my head on his shoulder. This was very natural in our family, nothing weird going on whatsoever.
Maybe this is a cultural thing. My father is Greek, very mediterranean and very affectionate. In his culture, adults (men and women) kiss on the cheek when greeting instead of shaking hands. It’s not unusual for two men or two women (friends) to walk hand-in-hand in public. Physical affection is very natural and expected.
