Senile old fart automatically assumes that sexual attraction is for procreation and the propagation of family lineage, and not for recreation and entertainment.
Frankly though, with that kind of daughter, daughter-in-law and wife, I'd keep my mouth shut about it.
And, Old Fart Lee, it's not like the genes in the Lee family were that exceptional... after all, you got an albino grandson. What are the odds?
No looks, no quality genes, and not that great in the personality/character department.
Honestly, what are you good for?
