In order to cause my brother to miss his interview, I'm thinking of not changing the clock for daylight savings.
For what reason are you trying to upset your brother?
It's the only thing I can do to harm his chances at succeeding in the interview.
You should always help your brother get that job he dreams about. It's mean to play prank on unsuspected individuals.
He's getting that interview for purposes that he doesn't tell me about. I just want to make him mad.
This is a cruel prank and interfering with the potential of your brother gaining employment is wrong. You should be supportive of his chance to do well and trust that there might be a reason he hasn't told you everything.
