[after hearing a noise at the front door at about 2am in the morning]  David : [tears open front door to see Mr. Haskins kneeling on porch]  Mr. Haskins : [bolts up]  Dr. Calloway. I'm sorry. I didn't mean to disturb you at this hour. [hands over small envelope]  Mr. Haskins : These are the keys to the individual rooms in the house. I thought you might be needing them. I meant to be give them to you earlier, but I forgot. I'm sorry. David : [looks at the keys and then glares back at Mr. Haskins]  It's a little bit late to be delivering keys, isn't it? Mr. Haskins : Wife and I are going to Canada early in the morning, so I thought I'd just slip them under your door while it was still on my mind.
