“Negligence is either failing to do something a reasonably prudent person would have done or doing something a reasonably prudent person would not have done, under the circumstances, that causes injury to someone else. . . The basic elements of a negligence claim are: a duty on the part of defendant toward plaintiff; defendant’s breach of that duty; and harm to plaintiff caused by the breach.”
“The statute of limitations for most negligence claims is two years. As with other claims, a negligence claim normally accrues upon occurrence of the last act necessary to complete the cause of action.”
