If someone asks most likely I will say ok but if not I will box that hand away with a quickness. They are invading my personal space. My old workplace this one girl went to touch my hair fully knowing I don't like it, without hesitation I box her hand away accidentally hitting her in her mouth. Did I apologize nope, my response was "that is what happens when you invade personal space damn well knowing I don't like it" After that not one person touched my hair.
