lol, i think its another form of complimenting your hair. if you have people just become attracted to you because of your curls and have a desire to touch them it's because they are fascinated at how good it looks. yes, it is rude to have strangers just touch your hair. i always tense up because i always get the ones that walk up behind me and tug at my hair, which burns me up. if you wanna touch then touch nicely. dont pull.
