Kate, when a women is shorter than me. Its impossible for her to assess how much taller I am. I've had many think I'm 5 foot 9 or something. When I tell her I'm 6 foot she'd like, Wow! That tall.
Every day people say, I know this women who's as tall as you and I always say, she's probably smaller. Then, I meet this supposedly giant women and yep, she's not as tall as me.
I'm not sure she'd be so enthousiastic if you told her you were 6 foot 2 or saw you taller than all men around. And, even then, in a normal setting she'd just assume your wearing heels.
In a way, its a good thing that people cannot assess height that well, it makes height really an non issue except if your also bulky horizontally. That's why I try to wear fitted clothes. I wore loose clothing all my life to look bigger, and it brings back very bad memories.
