Where Does the Height Come From?

One comment I get from readers once they meet me is, "Oh, I didn't expect you to be so short."  Or, "I thought you'd be taller."  Frankly, I hoped I would be, too.  I fully expected my three granddaughters to be taller than me, but by age  eleven???!!!!  Jazmine, at sixteen, is 5’ 7” and often wears heels so she towers over me.  Bailey is tall and lean and at twelve she's already 5' 4".   Maddy Rose, the youngest of the three girls (and the one who shares my birthday) shot past me this summer.  In heaven I'm convinced I'll be taller so at least I'll be able to look everyone in the eye.
