This weekend we drove from Norfolk to the South Coast.
Sally is a very good traveller, so she settled down in the back seat (safely strapped into her travel harness) and went to sleep.
Two hours into our journey we were on the M25 and approaching the turn off that we would take if we were visiting my Dad (who she loves dearly and who she stays with when the OH and I go away without her).
At junction 18 she sat up in the back seat and started crying excitedly. This continued until we were about a minute or so past junction 17, where we would normally turn off. She then let out a big sigh, settled down and went back to sleep for the rest of the journey.
I can't think of any explanation other than she knew exactly where she was - but once she realised we weren't going to visit her 'granddad' after all she stopped being excited and settled back down for more snoozing.
Anyone else with an amazing cocker navigator? Who needs a sat-nav!
