| One of the most common grammatical mistakes is also one of the easiest to learn to avoid: |
She/Her and Caroline were very relieved to see the fire engine coming.
Is she or her correct? To find the answer, separate the 2 people and put each one in a separate sentence:
Caroline was very relieved to see the fire
engine coming.
She was
very relieved to see the fire engine coming.
Therefore, "She and Caroline were very relieved..." is correct.
Matt Damon was talking to Ben Affleck and I / me.
To find which one is correct, take Ben Affleck out of the sentence and you will automatically hear which one is right:
Matt Damon was talking to me.
Therefore, "Matt Damon was talking to Ben
Affleck and me."
