The rules of wedding etiquette are constantly changing, making it difficult for modern brides, grooms and guests to find up-to-date and correct information. That's why we launched #MannersMondays, a series in which we ask our followers on Twitter and Facebook to submit their most burning etiquette-related questions. Then, with the help of our team of etiquette experts, we get you the right answers to your biggest Big Day dilemmas. Check out this week's question below! "If you are invited to (but do not attend) someone's wedding, do you have to invite them to yours' Also, if you attended someone's wedding years ago but no longer speak to them on a consistent basis, must you invite them to yours'" Anna Post-- great-great-granddaughter of etiquette guru Emily Post and author ofEmily Post's Wedding Etiquette-- is here to help us answer this week's question. Find out what she had to say below: No, there is no requirement that you invite everyone who has invited you to their weddings in the past, regardless of whether or not you attended theirs. As you note, time can change relationships. While a wedding can be an opportunity to rekindle friendships, look first to create your guest list from those who are present in your life on a regular basis, and then to special friends and family you may not get to see as often but to whom you are close. From there, if there is still room on your guest list, consider others with whom you are in less frequent contact."
