Guys 1rst person or 3rd person?

You could shift between them if you'd like. Some scenes just feel right in first person while others need a wider view. You could just write the scene in whichever perspective and just make sure the reader gets to know which it is

It's just a short text I won't have enough content to switch back and forth

Hmm I think I'm going to go with 3rd person because like I need to practice
