Why is it not always necessary to exclude a subject pronoun before the verb in spanish? write your answer in english and give an example in spanish?

In Spanish, the verb forms often make the subject pronoun unnecessary, and when that's the case the pronouns shouldn't be used unless there's a reason to.

Example: Nosotros abrimos la tienda todos los días.

Abrimos is the verb.

Hope this helped! :)
