Walk in the Park?

Cara: " No Bruce, I don't think this is going to be a walk in the park"
Bruce: "Really? ... We have our leads on and we are in the car"
Cara: "But look what's in the seat behind you"
Bruce: "Biscuits??" ......... Tail wagging in anticipation.
Cara: "Nope. Our food in BIG bags - AND our beds - AND our rats - so it looks like we are going somewhere for a long time"
Bruce: "Well I hope it has got rabbit burrows" Doleful look comes over the eyes!
Cara sighs!
