My sister and I always have a writing session together at least once a week at our local bookstore. Usually, while we’re there, one of us asks the other a grammar question.
Sometimes we can figure out the answer, sometimes we can’t. Sometimes we look it up on our phones, other times we’re too lazy and just write down whatever. We know what we mean. We can look it up later.
Though there are some people who love to argue over grammar issue with my sister and me.
Use “I” when you’re referring to yourself before the verb in the sentence.
John and I ran three miles this morning. (The subject is before the verb “ran”)
Use “me” when you’re referring to yourself after the verb in the sentence.
Andrew ran three miles this morning with John and me. (The subject is after the verb “ran”)
Think of “I before E except after C.” It has nothing to do with this, but it’s an easy phrase to remember. Also remember that not only does I come before E, but it also comes before the verb. Maybe that will help, maybe it won’t.
