Hello Scrumpy,
No your O.K. perfectly fine, ......….how ever many of us at some time or other have a similar event
my wife when we were our shopping recently and parked the car in a really big carpark , later my daughter and i were sitting in the car and watched as my wife came out of one shop and headed towards a man sitting in his car,
i said to my daughter perhaps she knows him from some where or other, and has gone over for a chat, the man looked very concerned as my wife walked towards him giving him a lovely smile as she waved her hand as well, suddenly she realised she was waving to a stranger and the penny dropped ,
boy how my daughter, and i laughed, as my red faced embarrassed wife finally found our car , evidently she never seems to notice the make of our car ,well usually i am with her, and i wave to her when im in the car , how ever there are times when we all do some thing or other , so i suppose it shows were all human and can and do make the odd error from time to time,.
