I don't really think short people are more "troublesome" than tall people (I'm 6'4", btw), but perhaps part of what you perceive lies in a cultural bias short people perhaps feel.
I mean, think about it: In the fairy tales, the stranger is "TALL dark and handsome," not SHORT. The top cabinet in the kitchen requires a short person to get our a stepping stool to get something down, while I just reach up there and take it. Certainly, the plethora of such things out there could cause SOME short people to feel a bit annoyed. But "troublesome?" I don't think so.
