Cab Driver Details Relationship History

A cab driver utilized the trip from JFK to the financial district yesterday to offer a detailed history of his relationship. He and his wife had been together for more than ten years. They had their first child when they were both thirteen. A few years into their marriage his wife had an affair. He had a few retaliatory affairs. His wife then slept with a semi-famous R&B singer. When he confronted her about it she stabbed him. The driver attempted to show his wound, but found it difficult to drive at the same time and so gave up. The driver and his wife were still together. He said that he was still attracted to other women, but experience had taught him how that could 'complicate' things. He said that now he and his wife concentrated on keeping things 'spicy' in the bedroom to avoid the conflicts that plagued their early years. He said his wife appeared to be just a normal paralegal, but at home she was his 'little slut'.
He then asked his passenger how the passenger kept relationships 'spicy'.
The passenger did not reply.
The driver laughed. Ah, he smiled, I know how you are. Spicy.
