A story from when I was a little kid.

Back in the day, my Dad liked to go to the horse racing track to do a little betting, and he would bring myself and my brothers along. You know, give our Mom some peace and quiet for a little bit. This also meant that us kids would be able to get some concession stand snacks, like nachos. This was a big deal to us kids. Anyway, one Saturday as we were leaving the race track, some lady came to my Dad and said "Oh how sweet of you to take your grand-kids to the track with you!". My parents had us a little later in life, so he could have reasonably been someone's grandfather at that point. My brothers and I, being little shits, chimed in with "Yes Grandpa, thanks so much! This was fun, we love nachos!". I don't remember if he corrected the lady, but it was a funny story we continued to tell for years and years.
