A couple of hundred steps toward my destination, by the time I reached the main walkway, my hair (I do need a haircut) was dripping water down into my glasses. At about this point, I encountered a youngish Asian woman under an umbrella, coming the other way.
She paused, scowled ; cocked the umbrella to one side and asked:
You want me to walk you?
Translation: she was offering to turn around and shepherd me back to dry land. I said no thank you but I must add: today's mitzvah.
Afterthought: Or maybe the point was just that I was looking really old. The other day at the tire store, some beefy guy in his 40s addressed me as "young man." Not a mitzvah at all.
