When To Use The Spanish Past Imperfect

Use  the Spanish Past Imperfect when you need a verb to talk about ongoing continuous action.

People who like to front load their stories use this type of verb. You know the kind of person who when asked, "how was your weekend?" goes into all the background information to set the scene. ("Oh my weekend, glad you asked... the sun was shining. The wind was blowing. the air was floating.")
At times this background information is relevant,  but to my ears all it sound like is BLA BLA BLA. This is helpful because bla bla bla kind of looks like the ending to the Spanish Past Imperfect endings for the AR verbs.

AR endings aba abas aba abamos aban
IR and ER endings ía ías ía íamos ían

The endings of the Ir and Er verbs sound more like (EEEEE Ya) which is the noise I am tempted to make while a run away from these big mouths.
