re: How old is it too old to kiss your son?

My Son turned 25 yesterday . I couldn't see him Yesterday, but he is here now and I just gave him a big hug and kiss!
On the flip side, My dad is a84 yr old Korean War vet/drill Sargent who has never told any of his 4 sons he loves us or ever kissed us. But his love for all 4 of us shows in so many ways. He was raised differently. Hell no one has ever seen him cry every.
