I know that the sentence above and many others are entirely common, but I would like to know if they fall into the category of "used because no one knows the rules" or if I am missing a rule.
If I say, "I saw the Smiths," I am really saying, "I saw the Smith family." If someone insists on using the assumed object, and we were transcribing the speech, would we punctuate it as a posessive? "So happy that the Johnson's visited" seems to be a misplaced posessive but "So happy the Johnsons visited" seems to be uncommon.
I am a stickler for rules, so if this is a rule that everyone breaks, don't apologize for them! I like to know the facts hard and straight.
Thanks!
