2.Denny was running at full speed through the Library when he saw a yellow sign that said "Danger Wet Floor". Two seconds later he slipped and broke his arm. An out of court settlement was reached saying: "Saint Mary's was negligent and that Denny's total damages amounted to $2,000 but that Denny was 25% contributory negligent."

Explain to Denny what contributory negligence means and how it will affect his damage award of $2,000.
