[Grammar] I vs me

[englishteacher79]

I understand that we use "I" when it's a subject and "me" when it's an object. However, what about the following:

1) "For me, I'm going to the cinema" This sounds right and not "For I". However, would this be correct, "For Mary and me, we're going to the Cinema"?

2) Which is correct: "Please register for Mary and I" or "Please register for Mary and me"

3) Which is correct: "Please do this on behalf of Mary and I" or "Please do this on behalf of Mary and me"

Thanks.

A handy trick to remember when you are trying to work out whether to use "I" or "me" is to take the other person (and the word "and") out of the sentence and see if it still makes sense.

Please do this for Mary and I. (Original suggested sentence)
Please do this for [STRIKE]Mary and[/STRIKE] I. (Remove "Mary and")
You are left with:
Please do this for I. (I'm sure you know this is not correct.)

Please do this for Mary and me.
Please do this for [STRIKE]Mary and[/STRIKE] me.
You are left with:
Please do this for me. (I'm sure you know this is correct.)

He sent an email to John and I.
He sent an email to [STRIKE]John and[/STRIKE] I.
He sent an email to I. :cross:

He sent an email to John and me.
He sent an email to [STRIKE]John and[/STRIKE] me.
He sent an email to me. :tick:

Hello,

I am a terrible reader, so I may have misunderstood your question.

I am sure that you know the rule that after a preposition, one always uses the objective form.

For some reason, I hear people (even TV newsreaders) break this rule.

For example, they might say, "Don't forget: This secret is just between you and I." (instead of "me.")

You should NEVER be confused again if you simply remember the very easy rule: The objective form ALWAYS follows a preposition.

So at your work, if someone says, "These donuts are just for you, he, and I," you will understand that the speaker had not paid enough attention in English grammar class. (The donuts, of course, are just for you, him, and me.)

The Parser is assuming that everyone takes an English grammar class. I think that's unlikely.
