I have just read Robert Jone's review.   Firstly I apologise to him for accidentally upsetting him.   We have three kitchen area windows overlooking the back yard.   I happened to walk into the kitchen from the hallway and see a car parked in full view with one two people beside it.   i continued to the end of the kitchen fully expecting to meet someone at the backdoor, when I reached it.   But as there was no one there I continued outside in order to enquire if any help was needed.

Until informed by the visitors I had COMPLETELY FORGOTTEN, that my daughter had mentioned that the Jones were being collected by relatives and she had agreed they could park in the back yard.   Apparently my daughter had promised to leave a note for me but we met before she had a chance to write it.  so told me verbally.  I had no idea which day this event was due and by the time I saw the Jones's relatives car I had completely forgotten about it, and as often people wanting to look at the caravan site park in the spot where they were they  appeared to me to be strangers in need of help.   

It was unfortunate that I had not seen the car arrive or the Jones walking out of the caravan site towards it.   

UNFORTUNATELY I also happened to be in a position to experience a DEJA Vu moment on the return of the Jones family group, and saw them in exactly the same position on their return in the afternoon.   I immediately recognised them and dismissed them as not requiring any assistance.   I was so astounded that they were in exactly the same position with two people outside the car, and again I had not seen them arrive, that I watched for a few moments to see them move.

I suggest that Mr and Mrs Jones visit again so that we can meet and discover that neither is as odd as this misunderstand seems to suggest
