I know your secrets, you can't hide them from me.
With your most earnest entreaties, you beg my benevolence, but I know the truth.
Your name I keep on my list, be it in good standing or not.
Reward or punishment come but once in a year, and to know which I will grant is an impossible thing.
I arrive in crimson and the purest of white, in darkness I prowl, unseen by all.
While you slumber I leave my mark; you will not know of my presence until you awake.
Heed my words, or it's coal you shall receive.
