you settle a case.
Especially when, at the start of mediation, the plaintiff wants $53,000 for her soft tissue injuries and pain & suffering (even though she was in two - count 'em two - previous auto accidents the month prior), and by the end of the mediation, she has accepted $5000 and mediation costs.
Plus, mediation is fun because you get to play with little wooden games and eat free snacks and M&M's and drink all the coffee you want. Oh, and you can bill for mileage!
It's the little things, people.
