I don't think it's so much rejection as it is fear that you are dealing with. People can struggle if they come across a person that has a facial problem that interferes with that person's ability to exhibit facial expressions that so many people get signals from. It can a challenge for someone when it comes to interact with someone with face challenges in that they don't want to disrespect that person and may not quite know what to focus on that won't cause the individual to feel uncomfortable that has the facial challenge.

I had a customer come out to my farm and he was a nice man on the phone and when I met him he had a big patch on one of his eyes. When I looked at him in conversation I did not want him to feel uncomfortable and I did my best to focus on the side of his face where I could focus on his good eye and go along with his emotional expressions. If I had time to get used to interacting with him to a point where I had time to get used to the patch, I would have found a way to feel more comfortable. That's me, not him and it's not rejection on my part either, it's simply more learning to adjust myself to seeing him to where the patch isn't a distration at all.
