So your mother was from the short side of the family? Or perhaps locked into the 60s lockstep. A dear friend of mine was 6 ft, married a guy 6' 4", and their children were also tall. As preschoolers, the children were thought to be slow and others treated them so. I hope you were able to escape this.
At 5'8" I was comfortably above the average, but not into the stratosphere. Hosting my friend's TipToppers Club, however, gave me a sense of life as a midget.
I have a tenor voice and most oft addressed as "sir" on the telephone. Thanks for sharing your experiences.
