Lucy funny ... Or smart

Lucy said to me today in the car,

"Mum why is there a 'b' on the lights?"

Sure enough there was a 'b' on the lights for the bus lane.

I didn't realize she knew any letters other than her name.

Then just now when I was reading her stories in bed she said, "MUM! 'S' is similar to a '2' and '5'! But not the same."

Very clever kiddo, very clever!
