I is not an object … def. –pronoun 1. the nominative singular pronoun, used by a speaker in referring to himself or herself.
Me is not a subject … def. –pronoun 1. the objective case of I, used as a direct or indirect object.
In other words, you don’t speak to I, give things to I, or decide between I and another.
Nor would me speak to others, give them things, or make the decision between a and b.
I would speak to him. I would give things to her, and I would decide between x and y.
And, you would speak to me, she would give things to me, and he might decide between you and me.
The bigger question, and frequent misuse, seems to come when combining subjects and/or objects … mostly the latter. What do we mean?
Here goes …
Please call Mike and ___ . (I or me?)
Terry was speaking to him and ___ . (I or me)?
Pat gave the paper to you and ___ . (I or me?)
How can you decide between her and ___? (I or me?)
Hint: take out the other person, enter the correct form, then add the other person back in … like this:
Please call ___ . (I or me?) Therefore … Please call Mike and me.
Terry was speaking to ___ . (I or me?) Therefore … Terry was speaking to him and me.
Pat gave the paper to ___ . (I or me?) Therefore … Pat gave the paper to you and me.
Get it? Got it. Good.
As we were saying … “I is not an object …”
