Guilty me or Guilty them

I was just feeling awkward as the person kept moving towards me. I did not know what could be an appropriate word to stop someone for making those subtle advances. What can you probably think of when you know his wife is also there? Maybe she will stop him.  Isn't it the most frustrating moment when they start touching you in the most uncomfortable manner while they simultaneously  call you their sister. It is the hardest to come out of such an uncomfortable situation. When know it is wrong but you feel helpless. Because they  are using the most appropriate social word "sister" that  if you flare up, people will call you attention seeking.

Well,  right at the moment when you need a savior, God sents you an angel. My sister read my  facial expressions, she pulled me towards her and gave me a hug and moved me away from the situation, 

I was angry at myself. Why I needed an angel? A savior? Why I needed a soldier? Why I could not speak for myself? Why? The society has trained my mind to think in a way that if someone calls me a sister they don't have cruel intentions. It is a beautiful relationship they cannot harass or molest you. Is that really true? What did I do wrong? Why am I blaming myself for someone else's disgusting behavior ? 

Does wearing a dress? Being confident? Being warm? Being nice gives people the wrong meaning? 

Guilty me or guilty them!!
