I think I have introduced myself in the former forum.But why I want to introduce myself for a second time? Because at that time I introduced myself as a man. Because I thought I wouldn't stay long in this forum,and I was sure to leave here when you know mor about Tibet and its history,so I decided to pretend to be a boy,for there are lots of men,and because of sexual discrimination ,discuss the issues with you as a boy maybe more convictive . But today I think it is time to tear down my careful disguise, for I want to be your friend perrmanently. you are right,singh,I am a girl. BTW,what antivirus software you choose,mine is not safe enough,so I don't dare put my private information in my PC.
