Our New Roommate Teddy

My two roommates and I are builders. We build each other up, and have a great time. We decide we need another roommate. Teddy applies. He is quiet, but calm. His references are glowing. We invite him to room with us. Teddy is a demolisher. We take care of things. He destroys them. We are free-spirited creators. He is grouchy and tries to extinguish our joy. We finally have to ask him to move out. We discover later that his glowing recommendation was from his mother. He set fire to her place when she kicked him out.
