2. My uncle was an old-time divorce lawyer and, in the days before no fault divorce, they had to prove some sort of basis ... even if, there was no real basis for the divorce, it just didn't work out. So, the quickest way to prove a basis to the judge was to prove infidelity ... either the wife would fuck the lawyer, or the husband would fuck the lawyer's secretary/paralegal and they would get pictures or video, making it look like it was a hidden camera. Nowadays, you don't have to prove anything. But, back then, it was basically part of a divorce lawyer's secretary's job to blow and fuck a client, or the client's husband.
