My FI and I have been engaged since 2008 (April), and had a wedding date set for Sept. 10th. 2011 (9/10/11, pretty easy to remember) by June of that same year. We asked all of our friends that we wanted to be in our wedding party by the end of 2008.
Fast forward to last week, we have several friends who are getting married right around our wedding date and I was calling to coordinate whos wedding was when, including a member of our bridal party. As he sympathised with all the weddings to plan around (because they were in the same situation) he mentioned a friend he had that was getting married a few weeks prior to his very own wedding. I kindly reminded him that our wedding was a "couple weeks" prior to their own wedding, and reminded him to check on the dates and get back to us. Well needless to say his other friends wedding did indeed fall on the same night as our wedding, Even though we had ask him to stand up in our wedding first, he bailed on us. Just kind of a crappy situation, not the end of the world considering how far we are from the wedding yet, just needed to rant!
