i snapped.. cause i dislike your procrastination.
i snapped.. cause i dislike your indecisiveness (i don't care if there's no such word.)
i snapped.. cause i'm simply irritated.

the good thing is, you will be safe if you don't get on my nerves. the bad news is, you won't know what will set me off.

good luck to you, the unfortunate soul who dares to come near.
