At the supermarket yesterday, I was looking blankly into the deli case, trying to decide if I wanted a jumbo tub of pasta salad or just a large, when a lady stepped past me to get a ticket. I realised I should get a ticket as well, if I wanted to get served, so reached out and grabbed one too.
The lady, realising I has been standing there already, had had just forgotten to grab a ticket, swapped her ticket with me to put me in front of her in the queue.
I was quite touched. Human nature can be a beautiful thing.
