It is rude to let down your friends
Tony promised his friends he'd finish his part of the presentation they have tomorrow this evening but sees a movie on tv he likes.
Tony wants to watch the movie tonight instead of working.
Tony puts the movie on record, finishes his presentation work, then finishes watching it.
Tony turns on the film and watches all night long and goes to sleep.
The presentation is a success and Tony's friends are happy.
The next day the presentation goes badly as Tony didn't prepare and his friends are upset with him.
