Past+Perfect+Continuous

__USES__

 * We use the Past Perfect Continuous to show that something started in the past and continued up until another time in the past. It is similar to the Present Perfect Continuous, but the duration does not continue, it stops before something else in the past.
 * Example: She had been living in New Orleans when the Katrina happened. Jessica sat down because she had been standing all day long.
 * We can use it to show cause and effect.
 * Example: Tony was tired because he had been running. They were mad at Lisa because she had been lying for weeks.
