Dear Yajeev Impersonator,
You may have thought that it would be funny to dress just like me (i.e. wear khaki pants and glasses with short wavy hair) so that Watson would think that you were me walking towards him on Capitol Avenue (when he thought I was attending a yeast genetics and molecular biology meeting in Toronto) and nearly choke himself to death as he strained against his leash to get ever closer to me (you).
Certainly, you learned your lesson when, as you drew nearer, Watson realized that you in fact were not me and that he had been duped, at which point, his leash-pulling ecstasy morphed to stranger-barking anger for toying with his innocent doggy emotions. If I had been there, I might have barked at you, too.
Shame on you.
