nivaN ji, thanx for your suggestion. I agree with you in one side but disagree from other side. Most of your suggestion is nice but my case is different. Friends(Brahmin) of mine says "kasto bhote rahech" to their own son when they do some food mesh. I know from their expression that when they hate they say bhote to chinese or mangolian. I belong to mongolian but they never say bhote to me and nobody said in Nepal. We are about 27 students (and 71 altogether including kids). Most of them are Brahmins and out of that only 2 or 3 used to say Bhote (to chinese/mangolian people) in fornt of me (other might say within themselves but not with me). I don't understand wheather their intension is to make me angry or ..... I agree with you that we must unite(especially when our country is facing problem, and when we are in abroad) and I know unity is Power. But this issue is making me crazy... I don't know what to do.... Plz somebody give me good suggestion. nepalithito76 ji, thanx for your suggestion too.
