He knows he’s not easy on the eyes, but all he wants is for people to look at him and treat him as they would normally. (It’s not the look of disgust that gets to him, but the surprise that they try to hide with the disgust, as if it were impossible or uncommon for someone ugly to exist in their precious little worlds.) There’s nothing that special to him, because he’s smart enough to know there’ll always be someone like him in this world, even if no connections are ever made.
It’s only later when he realises that some people are simply jerks, but are at least fair about it in that they also treat everyone else the same. However, almost all of them can’t take what they love to give, and so he continues to sit on the roadside, waiting for someone he can finally call special.
