[Edit] This was originally going to be JUST Karkat's memo, but then I thought... So now it's going to be whoever I want! :D . If you haven't read HomeStuck, go check it out.
This Memo includes spoilers for Act spoilers. If you haven't read them, I advise you don't read this until then. Also, this is SadStuck, grab your tissues, this oughta be a ride!
