Discrete actions are clearly defiend events that have a definite beginning and, in most cases, a definite conclsusion. See Ornelas v. Department of Justice, EEOC Appeal no. 01995301 (September 26, 2002). Examples include terminations, non-selections, failures to promote, transfer denials, suspensions, leave restrictions, officials reprimands, etc.
The Chateau Marmont in Hollywood has a similar connection to a celebrity death that it will never be able to shake -- and perhaps doesn't want to. In 1982, Saturday Night Live's John Belushi died of a drug overdose there at the age of 33.
Anne Frank died of typhus before Bergen-Belsen was liberated by the British on 15 April 1945. The precise date of her death is not known, but it was probably during the first two weeks of March. Her body was heaped up with hundreds of others in a pile beside the barracks. She has no known grave. But her diary remained.
