I don’t look like him
It isn’t enjoyable when someone tells you that you resemble another person, especially if it’s someone you don’t want to look like. In this situation, his pals told him he looked like Ted Kaczynski (better known as the Unabomber). He isn’t a model of health or fitness; not even close. You should probably cancel your evening plans.
It’s tough for us to accept that we appear like other people, but the apparent resemblance was staring him in the face in this instance. This guy constantly denied looking like the Unabomber until he read a book with his image on the back and had a significant epiphany. His face is nearly a mirror image of Ted Kaczynski’s! That must have been quite a surprise.
