You must use the simple present when talking about habitual actions or routines. On the other hand, we use the preterite tense to talk about things that happened at a certain moment in the past. Therefore, we have the following sentences:
______________________________________
In the Simple present:
<em>Miguel y Elena </em><em>cierran </em><em>la puerta</em>
In the Preterite tense:
<em>Miguel y Elena </em><em>cerraron </em><em>la puerta</em>
