So, mollified, I made my way home. I won't say the exchange totally left my consciousness, but I tried to put it in perspective. If the next sales clerk drops the "er", that's when I might get a little concerned. "Old lady" would put me in the ranks with Whistler's Mother and Miss Jane Marple. I'm not ready for my rocking chair just yet. Hmm. Maybe I should return the yarn and crochet hooks I bought at that store and check out the snowboards instead.
Come to think of it, it could be fun to wear the mantle of immunity we give to our elders. Seniors are allowed to say things in public that only toddlers and Donald Trump usually get away with. And, of course, I could start carrying a walking cane to give cheeky sales clerks the sharp end of the stick.
