How'd You Get so Smart??

This morning our home warranty rep, Bill, was over. He's been over a lot these past couple weeks to fix some final things on our house so Avery has gotten used to seeing Bill at our house. He was leaving and this is how their conversation went:

Avery: Bye, Biill!
Bill: Bye Avery!

Bill opens the front door-
Avery: Biill's truck
Bill: Yes, that is Bill's truck
Avery: Red truck
Bill: Yes, it is Red
Avery: Big truck
Bill: You're right it is big. How'd you get so smart? From your Mommy or Daddy?
Avery: DADDY!!

Thanks Avery :)
