Names and ages

You meet lots of people travelling, eventually you get to names and ages, frequently forgetting both. After meeting two people last night, we decided to skip names and use the “Zombieland rule”, where you’re called by where you’re from, and so spent the evening with Cricklewood and Glasgee. Then we played “guess my age” - Cricklewood was 19. After, with me, I said “no” to guesses in the high 20’s then Cricklewood asked if I could be his dad. I clarified that he meant “could I be old enough to be his dad?”, then said yes. Twice his age, ouch…
