 The great Gildersleeve has never plunged into the sea of matrimony, but he does like to dangle his toes in the water once in a while. A few days ago, he met a Miss Gloria McKinley, manager of the complaint department at Hogan Brothers. He hasn't had a date with her yet, but this afternoon, he has persuaded her to let him drive her home from work. Accordingly, we find him parked in front of the store with his motor running. I'd better leave it running, too. That policeman in the corner has his eye on me, and I'm parked in a loading zone.
