I have this friend who just got engaged and I am SOOO pumped for her! we know A LOT of the same people and we are pretty sure that they are going to want to get married next summer as well. They're invited to our wedding but it's too early to send save the dates and if they're like us, they will find a date pretty early on. We don't really talk very regularly (I found on FB she was engaged), but I want to make sure they know that we want them at our wedding and not to book on July 4. I feel funny calling or messaging her and like demanding July 4 be our day (I don't own it!) and obvi, I'm not going to be the B who is telling them when to make their wedding date but I just don't know what is the best way to politely tell them to save the date without sending the cards yet. What is a nice way to suggest to them to stay away from our wedding day??
