“Negligence is the omission to do something, which a reasonable man, guided upon those considerations, which ordinarily regulate the conduct of human affairs, would do, or doing something, which a prudent and reasonable man would not do…. It is an objective standard taking no account of the defendant’s incompetence – he may do the best he can and still be found negligent” - Baron Alderson, Blyth v Birmingham Waterworks Co, Ex D 1856, 11 Ex 781
