A conversation of 5-year-olds

Here is a conversation between my son and his, also a 5-year-old, cousin A.

J: I'm going to Kindergarten next year.
A: Me, too!
J: But I'm going to Kindergarten that people are speaking Japanese. (He meant his Japanese friends who speak Japanese are going to the same school.)
A: Oh.
*Silence*
A: I'm going to just regular Kindergarten. You know, people speak regular.
J: Regular?
A: Yeah. Like, you know? We say "Hi" and stuff.
J: Oh.

I didn't know two 5-year-olds could carry such a conversation - actually listen to the other person and think through responses. It was so cute to see two of them being excited to go kindergarten next year and talking about it.
