"Her and I" and "Him and I"

Anyone else notice "him and I" and "her and I" becoming commonplace? I hear it constantly and in my experience, my more educated friends are more likely to do it (along with "...and I's," but that's another gripe for another time).

How do you not know "her and I went to the beach," or "him and I are seeing Taylor Swift this weekend," is wrong?

I wish it didn't bother me but it's worse than nails on a chalkboard. It's all I can do not to scream at the person saying it, especially the friends I have who do it ALL. THE. TIME.

Am I nuts? (Don't answer that.) Also: Help.
