The replies are so funny, I haven't laughed this hard at a thread in a long time.
The waving off at the door was always a running joke in our house.
We grew up in a posh suburb of a city with two sets of cousins nearby; the 'city cousins'. School holidays would always be spent on 'the farm' visiting our grandparents and our 'country cousins'. Absolutely brilliant times. Country cousins lived in a very rural part of the country. Whenever we would pull up outside the house they'd all run out, hundreds of them (ok 8) and surround the car all noise and excitement and welcomes. When we'd leave they'd all be lined up outside the house waving us off and we'd watch them getting smaller and smaller in the rear window.
In our Big City life a wave from the door as guests walked to the car sufficed.
We inevitably became asshole teens who were bored of the farm but had to go, then hit our early twenties and didn't bother anymore. Driving off we all refused to wave back instead sneering at how hick they were lined up outside the house. We were very sophisticated and successful by then and assumed our Country Cousins would be wowed by our stylish clothes, impressive jobs and innate coolness if we ever crossed paths (unlikely).
A few years later some events threw us together and I realised all Country Cousins now lived in the city not working jobs but each running their own successful company, owned property, charmed our friends and generally made us look like utter knobs in comparison. They could buy and sell us by that point while we could barely afford the rent in our filthy hosueshares. Of course as they were inherently great people they still seemed delighted to see us and hadn't ever picked up on our earlier arrogance as well, they were busy living their impressive lives and I love spending time with them whenever there is a chance.
I'm middle aged now, the farm is gone but their mother still lives there. I took my LO there last year, it was adorable to hear her screeching when we pulled up outside to the sight of my auntie, one of my cousins, his wife and four little kids standing outside the house, the dogs barking and smiley faces all round.
The day we drove off, I watched my daughter in the mirror waving manically through the back window and my heart sang.
Keep waving them off OP, it's lovely.
