I always imagined that as soon as I got engaged, I'd call all my friends to come to a restaurant or bar for a joyous impromptu celebration. (Our parents live very far away.) But I just learned that American tradition says anyone invited to the engagement party must be invited to the wedding. We won't know how many guests we can afford for another month at least. I don't want to offend anyone, if this is true, but do people really expect an invitation to a formal wedding if they were invited to an informal engagement celebration? If so, I guess I'll just skip the engagement party.
