I was taught to not squinch my eyes in the sunlight and to keep my mouth shut while putting on mascara. I taught my DDs that too. I have very few wrinkles around my eyes and I think not squenching in bright light is the reason. Not opening your mouth while apply mascara/eye make up is suppose to help you not feel anxious or nervous. A dear lady in my church when I was a teen went to a famous finishing school in Europe with royalty and she always tried to teach all the young girls about having class and elegance. Her family lost their fortune soon after she was educated in the art of being a lady. She was always a lady and has inspired me from the day I met her.
