overheard at work

my co-worker overheard this conversation between a few girls sitting together at work the other day.

child 1: when i grow up i want to be a kinder teacher so i can work with teacher 1 (a.k.a. my co-worker) and teacher 2 (the morning teacher)

child 2: you won't be able to do that because they'll be dead by then

teacher 1 (who overheard her name and started listening to the conversation): i'm only 26! i won't be dead then!

child 1: oh. well teacher 2 will be (she's in her low 5os)

teacher 1: i'll think she'll still be around too

child 1: yeah, maybe
