Good afternoon, anonymous. Boy.. you’re as vulgar as you are confused. So it’s actually the author’s solution that the highlighted bit refers to. I believe that pretending to be appreciative of and interested in a catcaller is likely to elevate their confusion when you get to the inevitable “Ok, I don’t want to talk to you.” I think that clearly communicating your disinterest rather than feigning friendship for 60 seconds or minutes is a much safer solution. Please read comments thoroughly before replying or highlighting. Thank you.
