OA lang ba ako kasi I expected something in return?

I always try to help my classmates whenever I can that means I would help them with their research, print their papers for free, give out answers and others basta kaya ko I'll help them. Nung isang araw we our tc gave us a new project to work on, groupings siya. As usual I tried to help my classmates and I shared my answers again kaso dito na ako medyo na disappointed haha kasi after ko i-present our teacher made a comment mali raw yung gawa namin and I felt disappointed sa sarili ko kasi bakit di ko a double check pero ngl na shock din ako sa mga kaibigan ko kasi di nila na sabi sakin na mali pala yon kasi diba i shared my answers sakanila and kapag may mali sa research nila or other works I always correct them talaga kasi strict teacher namin tapos pag sakin kahit ngayong time lang di nika ako natulungan:( okay lang sana if di nila alam na mali pala yon pero nakita ko mga gawa nila after mag present e tyaka tinanong ko rin sila if okay na yung ganon na answers I'M NOT BLAMING THEM nagulat lang talaga huhu alam kong mali ko naman talaga yon pero yeah

p.s. sorry if diretso yung pag type ko 😅
