How can I get rid of unwanted people?
Stop associating with them or distance yourself from them or even change your telephone number.
stop talking to them...they'll eventually get the hint.
You can ignore them since this works particularly well for the type who is annoying merely to get a reaction from others. You can also annoy them if they are clingy and also tell them to go away and leave you alone.
ask them to leave
The question wasn't clear to me. Can you explain what kind of "Get Rid Of" I would like to have a chance to answer your question.
Well, considering it is currently illegal to kill anyone, you are outta luck<3
