Pure virtue
Too explain I will give an account that happy happened to me.
I was annoyed with my son because he asked me to pick him up from school because miss the school van.
It happened another day n he was very apologetic however i went to pick him up. On the way back i asked him what happened. He explained that he clean the classroom. then i asked him isn't today the last day of the class?   then i asked him who else was he said no one. ask him whether teacher there? he said no . then i asked him other students were there he said no . Then I ask him why did you do it ? he said the teacher gets annoyed when class is dirty.
