Explanation:

Use of past tense: We can tell that you are talking about a past event by using the simple past tense. The past simple tense stresses that the action is over, in contrast to the past continuous tense, which is used to discuss past events that happened across time.

Use of modals: Modal verbs express potential, intention, capacity, or necessity. They are used alongside the main verb of the sentence because they are a sort of auxiliary verb (helper verb). Examples that are frequently used include should and must.
