Sometimes, you just have to delete people from your life. 

Easier said than done. You can't just highlight the person and hit the delete or backspace key like you can in a document. No, depending on how many social network sites you are on and interacted with your object of deletion, it's almost impossible. And don't forget about your phone numbers that were given freely.

I've had to delete people from my life over the years because maintaining the friendship became cumbersome. They had so much 'me' going on it got to be tiresome and they were just toxic. To much drama!

Unfriending and blocking a person will work in the short term if you don't want to go to the trouble of establishing new email accounts and then making sure your other, non-deleted persons are informed.

You can block numbers, but some carriers only give you a 90 day window and then you have to go back in a block the number again.

There are a few people that I have deleted and blocked due to them gaining creeper status. Some have become sanctimonious pricks. They know who they are.
