LOL: my mother used to tell the story of when 96 year old Grandpa came to live with her. She had to ask the home health nurse about how to stop him from playing with himself, because she kept walking in on him (door wide open and all). According to the nurse, if you stop giving him lots of hugs, and keep touching to a minimum, it will decrease (and it did!)
So YES, I think he was enjoying himself!
Usually they say that genes sometime "skip" a generation so I feel like if the fathers were made to be grandfathers (they would have to look older of course) and Yuuen and Emba were the grandkids I would have liked it a bit more. Also, I feel like it would have added a whole other dimension to the story because you would have had grandfather, father, and then sons. :)
