Control.

What happens when you let certain emotions take over
in a situation? Maybe, you'll let fear take control
and maybe you'll be the one to walk away without
getting an apology that you deserve. Maybe you'll
let anger take control and, just maybe, you'll
finally take a stand for what you've been holding in
for such a long time. Maybe, you'll just have no emotion
at all, just let it all go. When you work so hard for something,
and see it all go to waste...it's always painful to see.
You can call it your mistake, and then realize it as a regret,
or you can bottle it up and just forget it ever happened.
Either way, you'll learn something, and it'll probably come
back to haunt you....but that's to the extreme. Let things
just go how they're supposed to flow.
