Nuisance
1) Is an action (in legal terms) by a person/firm, etc which affects the 'reasonable comfort and convenience of life' of others. It is a crime if the nuisance is 'public' (ie where more than one or two persons, but not possible to say how many, are affected) or a civil wrong (ie tort) if the nuisance is 'private' (ie affecting only one or two persons).
