My grandparents lived in a granny annexe joined to our house which we could get to through a door off our kitchen. As children, we were always running in and out, often having tea with them or watching TV if another channel was on in our bit of the house.
ANYway, one day when I was about 14 or so, I walked in there and they hadn't heard me. They were standing in their kitchen, hugging each other, lost to the world! They didn't hear me, and I left quietly. It moves me to tears every time I remember that, because at that time they'd been married 50 years and still loved each other so much. I decided at that moment that I wanted a marriage like that, and vowed I'd never divorce. It's my most precious memory of them, and they never even knew about it!!
