Why is the verb ler kept in the infinitive form after decides?

In Portuguese, when one verb follows another, especially after verbs like decidir (to decide), the second verb is typically in the infinitive form. This is similar to English, where we say "decide to read." Therefore, "decides ler" corresponds to "decides to read," keeping ler in the base (infinitive) form.

Lá dentro literally translates as "in there" or "inside." In this sentence, it specifies that the reading activity occurs indoors or within a particular enclosed space. This detail contrasts with spending time outdoors and adds context regarding where the activity happens.
