Teaching Calder to use the word "prefer" and wondering how much he understands.
Me: Calder, do you prefer apple or orange?
Me: Do you prefer orange or grapes?
Me: Do you prefer Mei Mei (Ethel, who was sitting beside us, supposedly doing homework but really listening with a spark in her eyes) or Mommy?
Calder: Mei Mei.
Me: Do you prefer Mommy or Daddy?
Me: How is Mommy feeling?
