LEAVE ME ALONE!!! When is it ever nice?

In many conversations that I've had with my friends we always talked about when to tell someone to leave you alone and how to say it (or how not to say it). I for one am a really impatient person and get easily frustrated by someones annoyance. I really don't understand why someone has to keep up their stupidity knowing that it's upsetting and that they really should stop. For example, on several occasions I've came across a guy who decides that they want to call me a hundred million times after i didn't answer the first time and then want to text me a good ten times after that AND also hit me up on AIM or BBM. If i ignored and didn't hit you back what makes you think harassing me is gonna get me to pick up the phone. If i do pick up however expect an attitude or a cursing out cause i don't have time for the pestering. NOW as for telling someone politely to leave you alone, i don't think there's a right way to tell someone that but its just the way you go about it. Explaining to the person your reason for not wanting to deal with them and being upfront and honest minus all the rudeness and disrespect may result in a better outcome and you may get your wish. As for all the harrassers out there get a clue and move on, if and when the person is ready to speak to you let them do it at there own will not yours.
