If you begin with a verb referring to past time, keep the verb forms in the past. The same rule applies to tenses throughout a composition.
The verb after a since clause of time is generally in the present perfect tense.
Express an improbable condition by the past tense and use the conditional in the main clause. This use of the past tense doesn't indicate a time but a degree of probability.
Use the simple past tense to express a habit in the past, and not the past continuous
Use the past continuous tense to describe events in the past happening at the time another action took place: I was walking to school when I met him.
