Dear... Fake Friend
Imagine how hurt I felt when you tuned me out in favor of your other friends. You don’t know how I feel, nor do you care. Our years of friendship meant nothing to you. You can just throw them aside when they don’t do what you like, huh? I’ve never run into a fake friend like you in real life, however, so this hurts a lot worse than anything any friend did online to me.
I think you should reconsider how you treat other people in the future, so that you don’t wind up using friends to mistreat your other friends.
Farewell, fake friend. Clearly, our friendship didn’t mean that much to you.
