You should reserve the right to wear what you like and I will reserve my right to think, “My eyes! My eyes!”
Actually I often have bad thoughts about other people’s footwear. I only think the thoughts, though. Do I comply with the ‘be kind’ directive? When I retire and no longer have to do a morning commute (current estimate puts this at age 70 so not any time soon!), on my last morning I will ask each and every one of the women on the platform who habitually wear shoes I consider to be hideous, “why would you make your own feet and legs look so ugly WHY WHY WHY????”
