What cause the decrease in the use of postal services?​

The evolution of technology is what caused the decrease of use in postal services. People do not need to send letters anymore, as they can simply send a text, email, or call a person in any part of the world that they wish to speak to. It is easier and more efficient, so more and more people are opting to use technology rather than the written letter to speak to people long-distance.
Hope that this helps! ^_^

With technology forever evolving the need for postal service becomes obsolete with tech like drones or bots delivering packages.Mail itself also becomes unnecessary when bills,messages,and advertising can be emailed to people

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
