From which point of view is the sentence written? We laughed so hard that milk came out of our noses.

first person

second person

third person omniscient

third person limited

So it’s first person because they use personal pronouns. The one they used is “we.” second person uses you. Theirs person limited means the author is telling the story but only knows as much as the character knows. Third person omniscient means the author knows more than the character knows. Hope this helps
