I've been getting that 'look' from elderly ladies lately.
I'll be in the supermarket, probably with both kids. They are full of beans (or free countdown fruit for kids, more accurately) and I just want to whizz through and get the shop done. I'm in some sort of harried rush, multitasking with the list, the kids and the bags.
I walk past an elderly lady in the aisle and she will look at us. And I can see her eyes soften and her face go into a half smile. Sometimes she will say nothing, and sometimes she will make a passing comment about 'oh they are lovely' or 'oh it goes so fast.'
