John felt as if his heart skipped a beat when he saw the bear. He had forgotten how beautiful and perfect it was. He was surprised how badly he wanted it, this old, matted, one-eared teddy bear.

He bought the bear, then skipped back to his car, bursting with anticipation. He imagined the many pranks they could pull on his roommate and the funny games they could play.

He spent the rest of the day building a magnificent pillow fort in the living room, his laughter echoing through the apartment. He then proceeded to have a tea party, pretending to be a distinguished gentleman hosting a group of bears.
