Wednesday wanted you to look after Thing while she went to San Francisco to visit Enid over the holidays. Wednesdays exact words were, "Take care of him. and by care I mean provide him with skin care products, he'll go deranged without his perfect cuticles. And I don't want him complaining to me when I return." and yeah, then she left him with you. So now your just sitting at your desk in your dorm room, starring at the sentient hand which was just....walking around on your table.
