Pronoun Case Errors

Before I entered the class, I had no idea what a case was in the context of pronouns. Now, I have a general idea, but still struggle a bit. Progress! The concept of object and subject identification is a bit difficult to me, and so is choosing the right pronoun without going with "it sounds right" all of the time. That belief there got me a few wrong answers on my assignment; I am at least glad I learned not to go with that assertion, which is more impactful than my minor failure.
