Let's say you were invited to a party. Would you ever, I mean ever, invite someone else to a small gathering without asking the hostess first or letting the hostess know in advance? I really want to know...under what circumstances, if there is one, is that ok? Cause I would NEVER do that.

Also, let's say you're at someone's elses house and you notice with your very own eyes that your child or pet has ruined something. Would you say something to the owner letting them know that you are sorry and at least offer to replace it? Seriously, what kind of person would actually SEE it and NOT say A WORD?

I'm far from being Emily Post's poster child...but aren't some things just common courtesy?
