I took my nieces and nephews the other day to the swimming pool. The youngest is 7 and the oldest will be 13 years next month. A guy (few years older then me) that I know from work (but he is not a coworker) met me when I was with the kids. Few days later we met again.
He asked - out of blue - we never really chat (I am not a chatty person): "So, did your grandchildren like the swimming pool?"
So - there it was - the very first question that I got regarding MY grandchildren. Aged 47.
I just replied: "No one has ever offended me the way you just did." And I walked away.
(obviously I know that some women my age have grandchildren - but they are babies, not teenagers!!)
