The Conversation

The conversation I overheard yesterday between CJ (3yrs) and his Aunt on the phone (on speaker phone) went something like this:
CJ: Is Oma there?
Aunt: No, she is at the grocery store.
CJ: What is she doing there?
Aunt: Buying food.
CJ: Oh.
Aunt: What did you do today?
CJ: We had school.
Aunt: Oh, you went to school?
CJ: No. School is at my house.  Some kids go to school, but my school is just at my house.
