Can you show an easy way to remember when to use I" or "me" in a sentence? (And please skip the technical grammar rules.)"

If you're not sure whether to use I or me in a sentence, remove the other person from the sentence and see how it sounds. For example:
  • Gordon drove Nancy and I to the library. [Gordon drove I to the library.]
  • Gordon drove Nancy and me to the library. [Gordon drove me to the library.]

Which one sounds right? If you picked the second one, Gordon drove me, you're correct.

Here's another example, which tests two pronouns in one sentence:

  • Her and me went to Miami Beach for spring break. [Her went to Miami Beach. Me went to Miami Beach.]
  • She and I went to Miami Beach for spring break. [She went to Miami Beach. I went to Miami Beach.]

Again, the second one shows the correct usage.
