The first thing that came into my head as I helped them up was to say, 'Whoa whoa whoa whoa whoa, what's going on here?', as if there was way too much falling down going on. The old man was embarrassed, acting perplexed about what manner of bedeviling surfaces he was unfairly forced to contend with. 'Oh, I fall down all the time', I reassured him. (But I don't, not anymore, since I got new winter boots.)
'Oh, bless your heart', his wife told me.
