...but to want to gauge my eyes out when people use "...and I" in the wrong place.
It's easy:
Say: "and I" when you would use "I".
I am going to the shop.
You and I are going to the shop.
Say: "and me" when you would use "me" in a sentence.
This is for me.
This is for you and me.
You wouldn't say: "This is for I", so what makes you think a second person makes a difference?
Feeling better already wearing my smug face.
