てほしいWant someone or something to act
てほしい expresses the speaker's wish for another person, thing, or situation to carry out an action. It can describe a private hope or function as a direct request when addressed to the person expected to act.
Who is expected to act?
A specific human actor is commonly marked with に. With weather, changes, abstract events, and other situations that nobody fully controls, が often presents the hoped-for event as a state of affairs.

Wanting an action not to happen
ここでは写真を撮らないでほしい。
I want you not to take photos here.
AnalyzeUse the plain negative verb form followed by でほしい when the desired result is that the action does not happen.
When a wish becomes a request
Because A says this directly to the person expected to help, it functions as a request. The ending leaves room for B to respond and makes the request less abrupt.
Keep the person who acts clear
たい normally expresses what the speaker wants to do, whereas てほしい expresses what the speaker wants another person or situation to do. させてほしい has a different role pattern again: the speaker wants permission to perform the action.
