TEACHER'S EXPLANATION:

>We used Simple Past to express the idea that an action started and finished at a specific time in the past. Sometimes, the speaker may  not actually mention the specific time, but they do have one specific time in mind.

> The use of didn't is more correct compare to the use of "unmaked".
