Hugs from friends are fine, wonderful even! But not from acquaintances. No one has mentioned doctors, dentists, and other people who have some professional reason to touch you. I really hate that kind of touch, pathologically hate it and avoid it when possible, or in the case of the dentist, take tranquilizers when I have to go. I would not get a massage if it was free and from the best massage therapist in the world. My hair is the exception, I love going to the beautician or having anyone play with my hair, I think because my grandmother used to twirl my hair with her fingers while she read us bedtime stories and I felt very safe with her.
