Discussing homophones with the 7 year old today...
Me: So can you use the word "to" in a sentence?"
He: Let's go... *thinking* Let's see, where's Michigan? Let's go there! Or Ohighway or somewhere like that. Do they still live in Ohighway, Mom?
Me: Who? Do you mean...
He: Like Uncle Eli and Aunt Mags and the rest of their family?
Me: Yes, they still live in Ohio.
He: We should go to Ohighway too then.
