Here's why:
* Passive Voice: The passive voice focuses on the action being done *to* something. The structure is "object + be + past participle of verb."
* Direct Object: You need something receiving the action of the verb.
Here's an example using a similar sentence:
* Active: Please open the door.
* Passive: Please let the door be opened. (The door is the direct object)
You could rephrase the request to make it passive:
* "It would be appreciated if you would go home." This is a more formal and polite way of making the request.
Or, you could use a different active verb:
* "Please be sent home." This implies that someone else is telling you to go home.
Ultimately, "Please go home" is best left in the active voice as it's clear, concise, and straightforward.
