Ezra (holding letters to his preschool teachers): I'm going to get lots of letters! Maybe Jen and Karis will send me dollars!
Me: Honey, you shouldn't ask people to send you dollars. I know Granny and Mema sometimes send you dollars in the mail, but that's just because they're family.
Ezra: No, they're not our family.
Me: Yes, they are. There's what's called "immediate family," or "nuclear family," and those are the people that live in our house--you, me, Jude and Mama. Then there's "extended family," and that includes your grandparents, great-grandparents, aunts, uncles, and cousins, and everybody.
Ezra: Oh. Are Katie and Blake my extended family?
Me: Yes, they are!
Ezra: Do they send me dollars?
