There have been a handful of times when people -- namely co-workers and guests at social gatherings -- have come right out and asked me, in the company of others no less, whether I wear a wig. Their tactlessness never fails to stun me, and the only response I can muster is, "Why do you ask?" The most common response is, "It always looks too perfect."
More appalling is when people touch or tug on my hair without my permission to "see if it's real." Sometimes people ask where I get my hair done, which I know is an attempt to find out whether I wear a wig. I fear that one day someone will pull it off.
