A few seats away on the metro sits an elderly lady with a strange fur hat perched on top of her head. She spends the journey chatting to anyone within earshot, smiling, singing, occasionally cackling like a particularly jolly witch. Some people smile back, others seem embarassed and are unsure where to look or how to react. She gets off at her stop accompanied by an elderly (and much quieter) man who is presumably her husband. As she leaves she waves enthusiastically to the people who had been sitting near her.
At the same moment a young girl of about six or seven years enters the train with her mother. For the rest of the journey she sings to herself quietly, and is unafraid to look around her at whatever or whoever catches her attention, making eye contact, smiling.
