I can't avoid it but I cringe when getting home from work and one of my neighbors is on his/her patio and tries talking to me... or just watches me.

One I'm really struggling with now is letting people know when they are bothering me; especially when they are trying to get me to make small talk with them. Most are perceptive enough, when my responses are clipped or I flat out don't respond, to back off. The ones that don't get it are excruciating. They just get louder and try harder. When this happens at work there is limited escape options. So I brood & glower & inwardly curse... then go home and have a meltdown.

People I suspect of not being able to leave me alone if I need it I avoid like the plague.

Also mirrors in public... I once worked up the nerve to greet a person walking toward me- when I smiled and said hello we both looked shocked and ran away. It was my own reflection, lol. That was a new level of humiliation for me.
