Conversation a couple of weeks ago between my mom and me...and Addison.
Mom: So how much was Davis's airfare to Atlanta for Christmas?
Me: Davis is free actually because he's a lap child under two.
Addison: (interrupting) Mom, Davis is NOT free. He's one and a half.
Yes, Addison has conquered all other sounds in the English language except for "th", leading now to confusion between the word "three" and the word "free". How do I explain this one to him?
