I wrote about my mom a few posts ago. My dad is just as great. Dad is 6'2" and a bit, so he's always been the big guy. My son, however, made it his goal to be bigger than grandpa, a feat he "managed" in his late teens. (not that it really was in his control)
For my sisters and I, his height meant we had to take two steps to his one, and when we were small it wasn't uncommon to see us running to keep up with him, which caused a few tears of frustration!
