A first for this Naturalista...tripped me out!

Today I experience a first... Today I received my first "stranger hands in my hair" experience...I wasn't sure how to react but I felt very accomplished as a Naturalista!!! What is it with people??? Do they think it's ok to put their hands in your hair? I equate this act equal to putting hands in my face! Am I over reacting? Or is this such a horrendous act that warrants such a reaction? Tell me about your first "strangers hand in your hair" experience and your reaction to this!
