Trains

I will be honest; sometimes L asks questions that I just don't know the answer to.  This time I made up an answer and she caught me.  L still loves trains so when I see one I make sure to point it out.

Mom: Lindsey, look! A train is out Joey's window!

Lindsey: Wow, where is it going?

Mom: I bet it is going to daddy's work.

Lindsey: Why?

Mom: To say "hi daddy".

Lindsey: I think trains don't have mouths. It is not going to say anything to dad.

She got me.
