On my birthday...
Oldest son: "Hey mom? Were people on Earth before 1981?"
Me: "Uh, since that's the year I was born... yeah."
Youngest son: "That's when people were still really new."
And another car ride:
Oldest son: "Mom, Dad, what's roleplaying?"
Me: "It's playing pretend but with a 'cooler' name."
Aerimor: "It's not that much cooler..."
