While I agree that the most important thing is that we be able to communicate, there are other considerations. Grammar was created to standardize our speech to minimize misinterpretations.

I don't know why it bugs me to hear, "Me and her" or "That was ok with Joe and I ", it just does. Sometimes it's ignorance, sometimes it's laziness.
Anyway, I see these abuses of the language as more "Dumbing down of America".
Over and out.
