see sosaysi buddy. thakuris claim themselves to b royal which they were some time before or recently. In no thakuri family they use aisiyo n gaisiyo ...siyo is heavily used in normal chettri family n bahuns family. long time before in common chettri n bahuns family they never used siyo..if they had to call their dad to have dinner "aa bau bhat khana aau" language changes its pattern, society always creates classes slowly with time. N if u go to Thakuri family u will surely hear baksiyo n baks. Thakuri chettris r also chettris, normal chettris r chettris, n khattri chettris r also chettris. To maintain their class they use this. There is no bad in using these kind of language. orginal ma ta hamra bau bajey le ta bau ama haru lai timi bhanthiye. suddo haru bistarai change bhayera nikaleko language siyo naramro ta chaina alik sabhya nai cha. tara orginality pani chodnu hunna..jo jo lai timi bhanna mann cha go ahead..n whoever r after siyo go after it but don comment abt it. ur tone, ur language is urs so y to compromise if someone comments. aba bujisiyo( aba buji baksiyo) ...kasto raggg gardibaksiyeko..gaibaks ek dui round LT diyera aibaks. aba nepal lai autonomous region banaune re tei bhara jai nepal bhannu sarai garo garidibaksine hoisincha so jai dharan bhannu parla parena bhane aru jun parcha tei bhanchu hai. ahile chai jai nepal.
