Say you’re coming up on a paper deadline, but your paper’s not ready yet and you need more time. This trick will only work if you are emailing the teacher your paper. Send an email that says this:
Here’s my paper. Have a good weekend!
Here’s the deception: forget to attach the paper. It’ll take at least two days before he says, Oh you forgot to attach the assignment! Could you email it to me? And by that time your paper will be done.
This will come in handy this week.
