Neck massage

While out and about today (had Henry in a back pack), Henry all of a sudden decided to give me a neck massage. I thought, "oh, that's nice. Maybe this can become an on demand thing?" So after he stopped, I tested it out and said, "thank you Henry, can you give me a neck massage?" Right away, he proceeded to rub my neck. His "rub" was more of a tickle, but I don't care, it felt good either way.

I definitely will be dragging this out and making it seem really cool to give your dad a neck massage! Unless he get too old and it just gets creepy...how old is too old?
