one day i went to school with a stain on my pants and i did n't realize it . i did n't find it until i came home . and no one told you about it ? maybe no one noticed it at all ? no they noticed . everyone was laughing at me but i did n't know why . that is horrible ! i hope they realize that their reaction was not exactly nice .
