Yesterday was my day to work at Son’s school. I overheard the following conversation on the walk back from recess:*
Kevin:[…some proposal I couldn’t quite hear]. Do you want to do that?
Steph: I can’t. I promised my friend Laura we’d live together and both be veterinarians.
Kevin: You could break your promise.
Steph: Oh, NO! I would never break a promise!
Kevin: Well, sometimes it happens, even if you don’t mean to.
Steph: Laura is my best friend. I would NEVER break a promise to her.
Kevin: Well, that’s just how life goes sometimes. Sometimes you break promises.
Steph: I don’t.
Kevin: You might forget that you made a promise.
Steph: I’ll never forget.
Kevin: You might when you grow up.
Steph: I’ll never forget a promise to Laura.
Kevin: Well, then. I think you must be an elephant. Elephants never forget. Humans do, but elephants don’t.
