Practice mistress you use during law school so that if your wife finds out you have nothing to lose as opposed to the real world mistress that you get once you are out of law school and making big money.

The law school mistress doesn't necessarily have to be up to your standards due to the fact that it is temporary and only practice for the real thing.

Sean: "Don't worry if you don't pick well, it's only practice."
