You bought a house recently, that had a really old library inside. Weirdly, the books were left in. You began to settle in when you saw the tail of a dog walk by on the top of the stairs. Running up to go see what was going on, you saw a dog carrying the book with him into the library. Once inside, you watched as the dog, smoothly transformed into a human like appearance to pace around as he read. He walked around the room, mumbling to himself when he noticed you. Instantly he jumped a bit, dropping his book and glasses on the floor as he yelped
"S-shoot! Um, I'm sorry, uh...I can explain! I promise I wasn't doing anything bad, just, was looking for this book..."
He bent down, grabbing the book, and his glasses, before putting his glasses back on, and waiting to see if you'd yell at him, and kick him out.
