"From me to you with love/etc........." are the common opening words in gift cards/etc. Anybody wondered why it was never written as "From I to you with love/etc........."??

Kitkattail:
"Hitchhiker: Yes, but that line of reasoning breaks down when you get to the verb "to be." People's ears will tell them that it is correct to say, "It is me," and so they will then also say, "It is Theodore and me." But since they were wrong in the first place, they will still be wrong when they add another noun. This is one of the best examples of why it is dangerous to rely on your ear alone without understanding the grammatical concept behind what you are saying. Ears need to be refined constantly. I'm still working on mine... sigh..."

I disagree with this. Native English speakers should rely on their ears. They are the best judges of what is normal usage in their native language.

As a native English speaker, these sentence are acceptable to me:

John and I went to the store.
Would you like to go to the store with me?
Would you like to go to the store with John and me?
Would you like to go to the store with John and I?
John got that sandwich from Suzie and I.
John got that sandwich from Suzie and me.
It is me.

I would never say this, however some people do say it and it is comprehensible:

John and me went to the store.

These are unacceptable:

Would you like to go to the store with I?
John got that sandwich from I.

This is acceptable, but sounds very old-fashioned:

It is I.

Overcorrection might be to blame for the confusion, but that doesn't change the fact that "with John and I" is acceptable.

People learning English as a foreign or second language might want to learn the prescriptive rules so that they are not stigmatized for using something that some people consider wrong. But they should also be aware of how the constructions are used in conversation.

I agree! John and I went to the store. Would you like to go to the store with me? Would you like to go to the store with John and me? Would you like to go to the store with John and I? John got that sandwich from Suzie and I. John got that sandwich from Suzie and me. My two cents: Who is there? It is me, John.                         It’s I who do the cooking and washing!                         It’s Susie and me who did the cleaning for you!                         It’s Susie and I who helped you when you needed the most! All acceptable to my ears.

Well, I'd say It’s me who does the cooking and washing! "Do" is incorrect there, in my opinion.
