I've always had crappy knees. They used to only react to specific triggers -- airplane and theater seats, mostly (and that one time I wore a 30lb costume in dress shoes a size too small for over eight hours straight with nowhere to sit, but honestly, I can forgive them that one) -- and I could hide it from most everyone.
And now, my damn knees barely let me walk the length of my building, and my coworkers, bless 'em, are trying to sneakily do my needs-walking tasks for me. Because I look so bad staggering around.
Two weeks to doc referral, and hopefully less to physio consult. It's all so dumb. Stupid knees, let me walk!
