A strange event occurred. My friend and I were walking and talking when a stranger asked him if he had a tissue. He said no (I said no too) and when she went away he pulls out a handkerchief and blows his nose in it. I ask him why he didn't offer his hanky, to which he states that she might have had oral herpes. I should have let it drop at that but pressed him that he should have offered. Eventually it comes out that he wasn't necessarily afraid of getting herpes as much as that she would try to sue him for giving her herpes in the case that he would get it from her. He said he read a story about some mother accusing a random person who gave her son a bandaide because he later got an infection and she successfully sued her. Do you go through similar thought processes when you see someone in need of help?
