My perspective on this issue is little different....Though i was never so lucky to leave someone on the spot.....and I have been victim of many incidents like that in my life...I admit I am not successful in such relationships.
I think we , girls are very much honest and pure in our relationships whereas boys ( may not be all but most ) are little moody and blunt type. We being girls need to know the reasons behind strange behaviors whereas boys needn't.
Moreover, when we kiss the world, the world would kick us in return for sure.....
hope you get me.
