Can they hear us??

Yesterday I was trying to explain to TJ why I could not stop what I was doing (DRIVING) and turn around and re-buckle his seat belt for the 3rd time.  He had to do it himself.  He asked WHY?  as a good toddler does. 

I respond, "Because we could get in a wreck." 
"What's a wreck mommy?"
"A wreck is like a crash."
"Oh, and the police come?"  He inquires.

(I digress here, this is because I was late to pick him up the day before and I tried to explain that I had to wait behind a crash and wait for the police to let me through.  This fascinated him)

"Yes, that's right buddy, then the police would have to come."
"Hmm.  Do they come because they hear the CRASH mommy, from the police station?"

"No buddy, we can call them."

"Oh, that's right.  Their number is 1-1."

Almost...almost TJ.
