Caroline,John always says "Typical! look at them..ahh yes lets get out before the caravan!" when people pull out in front of us from a junction.
He is also going through a phase where he is waving at fellow caravvaners and maintains nobody has waved back! I think he is being a `chicken`(hate that phrase though) and is waving too late so he will never know if they have waved back!! LOL
Your John waving at fellow caravanners reminds me of my youth in the 80's driving around in an MG Midget where we all waved at fellow drivers of the same marque,
best regards, Martin
PS. Lets hope this does not start a new craze (lol)
