You should not have taken the child to the cinema.
You should not have forgotten to leave a message for her.
You should have waited for them.
You should have put down her address.
You should have explained to her how to get here.
You should not have bought these shoes.
You should not have told her what you thought about her idea.
You should have seen the film.
You should not have written with a pencil.
You should not have eaten too much cake with your tea.
