The second anonymous note found its way under Shane's door during the day, while he went out briefly just to prove to himself that he still could without anything catastrophic happening. When he got home he stepped on the note before realizing it was there, gingerly lifting his foot to see what he'd set his foot down on.
He left the groceries he'd brought on the kitchen counter and went back for the note, picking it up and sliding it out of the envelope. Unmarked, of course, the handwriting clearly printed on a lightly decorated white card.
He'd been wondering since the night before who the anonymous person he'd spoken to had been. They'd been strangely understanding, to the point of being a little eerie, and they'd caught his interest just for their unique position. They seemed more willing to forgive his actions than he was, and he wasn't really sure what that said about the sort of person they must be.
The note seemed to cement this, and did nothing but heighten his curiosity. He set it aside and went for his computer.
