Some people are like hemorrhoids. They itch, cause general discomfort and can be a real pain in the ass. You put up with them because they weren't always that way and you don't realize the gradual change until it becomes very apparent they are a major disruption in your life. You endure the inconvenience because it has become a part of your everyday life. It's hard, but the only way to get peace and comfort is to snip them out; be done with them.
Yes, it's difficult to eliminate people from your life, but when you finally realize what a drag they have become on your happiness and well-being, you have no other choice. And do it with finality; don't drag it out!
Now imagine if that hemorrhoid is a relative!!!
Bless you, my child
