Sometimes, Narrative Tense uses a mixture of tenses. For example, when talking about two events that began and ended in the past, you may have to use both Simple Past and Continuous (Progressive) tense. Especially if you were interrupted while doing something.
As you may recall, Simple Past Tense used the Infinitive Verb + ed. For instance, you may hear a Native English speaker say:
“Yesterday, I walked to work.”
This is a Simple Past Tense. The speaker began and ended their walk yesterday.
