Where are we all day?

Lately Finn has been interested in where mommy and daddy are when he goes to Diane's house (his daycare). First, Finn and I were driving and he asks me,
F: mommy, where do you work?
Me: I work at a school
F: you help kids to talk mommy?
Me: Yes, I do. How did you know that?
F: you tell me mommy (I don't remember telling him that, but I am sure that I did at some point and am super impressed that he remembered)
F: mommy, when I get bigger can I come with you?
Me: of course.
Then I overhear a conversation between Sean and Finn the other night. (by the way Sean works part-time for a local environmental law firm)
F: Where do you work?
S: I work at an office
F: what do you do there? What do you fix?
S: I don't fix anything, but I protect the trees, animals and water. I help keep them safe.
F: From the bad guys?

It always amazes me how much Finn listens to what we say and really takes it all in. He is so curious!!
