Avoiding Pronoun Shifts
A first-person pronoun (I, me, my, we, us) refers to the speaker, a second-person pronoun (you, your, yours) refers to the person being spoken to, and a third-person pronoun (he, she, it, they, them, their, theirs) refers to a person or thing being spoken about. Avoid shifting person:
