I find it really weird for men not to tell their age. Not accusing women to be not confident about aging, but it's just that women usually conceal their age, not men.
But two weeks ago, when I was interviewing a man whose mother was a patient, it became a strange experience.
Me: "Your age, Sir?"
Him: "I'm old."
Me: "How old?"
Him: *chuckles* "You need not know."
Me: "I have to. I need to make a pedigree."
Him: *chuckles again* "All you need to know is I'm definitely older than you."
For me it's weird. A man, afraid to let people know him age? Puzzling
How about you? Do you know any man or guy who refuses to disclose their actual age?
