I'm feeling like cutting out my friend of 11 years out of my life.
What does he do that makes you want to cut him off?
He will bore me with his overly monotonous questions.
Sometimes friends do grow apart and it is understandable to end the friendship. It is okay to feel sad about it after all they were your friend for a long time.
I never liked that son of a bitch anyway.
I get that he may be boring and things of that nature, but cutting him out after 11 years may not be the best option. I would recommend just spending less time with them and seeing how you feel being away from them.
