The predicate affected object is used to relate an event to any object significantly affected in that event. The entity or entities in question must exist before the event, but may be either destroyed in the event (see the more specific predicate thing destroyed), or merely affected by it (for example, see the more specific predicates damaged object and object of state change). (affected object EVENT OBJECT) means that OBJECT is altered or affected in EVENT, and the change that OBJECT undergoes is central or focal to understanding EVENT. Thus, scissors are not an affected object in a haircut. The focal change in a haircut is hair getting shorter; thus, hair is a legitimate affected object in a haircut. The almost microscopic dulling that scissors undergo in a single haircut is a comparatively insignificant change with respect to a single haircut, considered as a haircut.
