''You got divorced a few years later, grandpa.''
My grand-father is 86 years old and I'm 20 years old. When I turned 19, he told me teasingly "You know, when I was your age, I had a house, was married and already had a kid on the way", to which I replied:
"You got divorced a few years later, grandpa."
I heard my grand-mother (his second wife) snicker in the background as he pat my shoulder in a "fair enough" way. It's small, but I still think it was funny.
