We have all had that experience when you're walking with someone, and they get a little ahead of you - perhaps you're walking with a slow child, or are 8 1/2 months pregnant and you just don't move that fast, or you are distracted by something shiny in a store window... And then you realize the person you're with is walking in the wrong direction, but they're now far enough ahead of you that you can't just grab their arm and nudge them in the right direction. We've all been there, done that, right? Well, imagine that you can't shout, yell, holler, or call-out to that person. Yep, that's my life.
