If I were invisible

Some of the things I wish I could be is to be invisible. If I were invisible I would have done many things I would not dare doing them at all. If I were invisible I would see people's life .the real one .I would see also the EXAMs that the teacher makes. I would also see what do people say about me.But being invisible is not always good .Like if you want to express your thoughts or even tell people if they were wrong .any way being invisible could make you satisfied or frustrated.
