O.C.G.A. § 51-1-4: Slight diligence and gross negligence defined.

In general, slight diligence is that degree of care which every man of common sense, however inattentive he may be, exercises under the same or similar circumstances. As applied to the preservation of property, the term “slight diligence” means that care which every man of common sense, however inattentive he may be, takes of his own property. The absence of such care is termed gross negligence.
