Good for you! Yes, I remember hearing a few school age girls giggling while riding the escalator behind me as well. I try to remember that most negative reactions come from guys who are secretly frustrated, fearful of exploring a hidden fascination with heels. I had to remember the old saying "never let them see you sweat" in order to get through some unpleasant encounters. I just try to remember all the positive comments I have received over the years, oftentimes from guys.
