Lately, it seems like everybody now says, "Me and my friend" instead of, "My friend and I". I mean you never hear it said correctly anymore!
I cringe when I hear public figures making this error. It's become so ingrained in mainstream communication, I believe it's past the point of no return. To always put yourself before the other person has become the rule.
Some might call that assertiveness, but I call it a sorry sign of the times.
