6 feet isn't just a measurement.. it's language. it means tall
I'm 5'9" and no one has ever called me tall, with or without shoes. I'm either called average or short. Certainly no one has ever estimated me at 6 feet. Never. I wish they would
This is over the course of my entire life. It's very difficult for me to imagine 3 or more people thinking I could be as tall as 6 feet within the course of a few hours.
