"My friend and I" or "My friend and me" Which is Correct?

This is something that confuses many people,

including English natives, but the solution is really

very simple. If you are not sure, the trick is to

take the other person out of the sentence and see

if it still makes sense (changing to the singular

when necessary).

For example:

Jack invited Mary and me to the party. - Jack invited me to the party. (Correct)

Jack invited Mary and I to the party. - Jack invited I to the party. (Wrong)

My friend and me went to the party. - Me went to a party.

My friend and I went to the party. - I went to the party.

My friend and I are both Capricorn. - I am Capricorn.

My friend and me are both Capricorn. - Me am Capricorn.

Now that you know the rule, if you listen to native English speakers you will see that, often, they also get it wrong. Don't worry. Just follow the rule and you will always get it right.
