Down South

I think any competent bus spotter would be able to identify that Lucy was down by the South Coast. She was on a trip with Mummy to see Grandad Ray and Great Nanny.

Lucy: "Grandad, Knock Knock" Grandad: "Who's there?" Lucy: "Doctor" Grandad: "Doctor Who?" ....

Lucy: "That's Daddy's favorite TV program"

That really is Lucy's favorite joke. Look - she's still laughing (admittedly Nanny and Grandad aren't).
