that is something that I do not get. 
She does not deserve to be groped. There is NOTHING that she does that makes this right. 
And yet, some of the ppl here continue to denigrate her and blame her. Yet, in that pix, you can see that the guy has his arm down towards her bottom and not on her waist or back. Likewise, you can see her skirt clearly lifted on her left side, compared to her right side. 
It is disgusting that ANYBODY is knocking her for this.
