Habit.

It's very difficult to break habits. Wether it be biting your nails, cracking your knuckles or flicking your stupid fringe out of your eyes, half the time, you dont even know you're doing it.
Chances are you're annoying somone.
But see, you started doing it for a reason. Routine is comforting. Habits are familiar. Why should anything you do or dont do, be because of anything but your own free will?
It's when the routine starts to annoy you that it's time to stop.
Problem is when it's somone around you who winds you up all the time and gets you rattled. When you're being made so uncomfortable in your own skin that you cant even think straight and everything just gets to you. When you're stuck in a cycle that just makes you sad. And it's not your fault.
Then what are you supposed to do eh?

Can you tell i'm a bit upset tonight?
