Guilt is a cellar door, cracked open

Guilt is something felt;
It comes from the inside out.
The cellar door cracked open, is letting the guilt peak through.
Guilt has no fear of light, the door just isn't open far enough for the guilt to show itself.
The strength of guilt, however, puts a strain on the cellar door like no other.
Something about that door makes guilt push just hard enough to annoy the door.
The annoying push on the door from guilt makes the door finally, CRACK!
Guilt slips through and makes the cellar door fell... guilty.
