YSK that, when referring to yourself as a direct object, it is grammatically correct to say "me" not "I"

For example, "He met my sister and me."

Just take out the other person and see how it sounds. You wouldn't say "He met I." You'd say "He met me."

It's just like that.

I'm not trying to be an obnoxious grammar nazi, this is just basic stuff that everyone should know and it's getting out of hand.
