sorry .
So today i went to school to give a exam (not real one but a extra curicullam type) (its on sunday bcuz of lots of postponds) so while exam we needed to put a sign of our beside our name on a sheet there were 2 sheets, in the first sheet my naem was not there so i passed on without doing anything to it after me there was a row of students too they putted their sign and passed on to next row in that row a child found someone has scribbled on his name he reported to the teacher then idk anything about it me and my frnd were gossiping and we disscussed some jokes and we were smiling our teacher saw me smiling and thought that i have done that scribling (but i have not even touched that paper) afterwards my sheet came i signed and everything got over and we did our exam while going home i asked our teacher (more of a rascal than a teacher) he said he thinks i have done it (then what could i could say more as if i say anything he will get angry and can..) so that time i started to hate him.. and.. now :
1. i have to find who did the scribbling.
2. i have teach this teacher a lesson.
Any suggestions?
