From 'Brother' to 'Enemy'

That's it! I've had enough! I can't believe he's using me all this time, I'm so sick of it right now! The fact that owing me 20 dollars from 2 years ago that I don't mind, but using my house as a bus station?! You're just lucky I haven't told your mom where you've been in the middle of the night, you F.A.(===>The guy I'm saying) I regret I even considered you as a brother.
