In the grocery store this afternoon, as Munchkin and I approached a line for the checker, Munchkin started making all sorts of silly sounds. He asked me what "they" would do when they heard him, and then he continued his noise. I didn't have the chance to answer before I heard an equally silly noise from behind me. A bent over old man (maybe in his 80's?) from the next checker line over was matching Munchkin's sound effects.
Munchkin was stunned at first, but then he broke into a big smile and said, "beep, beep!"
The man beeped back and then said, "When I was your age, the cars didn't go 'beep, beep,' they went, 'ga-goo-ga!'" He didn't sound like I do when I say, "ga-goo-ga" -- he sounded like a car.
