My wife and me are decluttering and giving away a lot of things. A week ago we asked a young neighbor if he would like to take some of them. He likes collecting minerals, thus he was very pleased taking parts of my wife's collection and some other pieces of our things. During our conversation he said "You're older people ..." but directly after this remark he apologized. We answered: "Don't apologize, you're right".
As I was a boy, my father of 50 years seemed being old for me. As my mother was in her beginning 70s, a young man I knew, told me, that he noticed an old woman driving the car I was sitting in. It was my mother. At that moment I came to know that she in fact was old.
I don't mind if somebody calls me 'old'. It's relative. More than a decade ago an old lady in her 70s called me "young man", but I was maybe 53 years old.
