This is all very familiar:
I was walking down a long hall at the gym today, and a flusteringly attractive woman was walking toward me.
I never know what to do in these situations. Obviously, given my druthers, I would just stand there in slackjawed amazement and openly gawp, but apparently this is considered “uncouth” in some quarters.
I normally go with the ‘staring at the ground’ option, sometimes with added blush. Sometimes I’ll be concentrating so hard on looking normal that I forget to blink, and my eyes start to water. I don’t think I should be allowed out in public, really. See the full post for his eventual solution, which turned out to be less than satisfactory.
