I apologize in advance for the length of this post and the venty-ness (I'm pretty sure I just made that word up) of its nature, but I'm at such a loss. My fiance and I just received the response card back from his godparents' (40-something) daughter's invitation to our wedding - with the names of her children filled in. I've never met these kids, he barely knows them... His godparents' adult daughter was invited with a guest, but apparently she has taken it upon herself to send her children in her place. I cannot even begin to fathom what the thought process was behind this and I have no idea how to handle it. We have no idea where to begin to address this. When we first started planning we agreed that we weren't inviting children (primarily because we don't want our mothers to end up babysitting instead of enjoying our wedding, which is what will happen if our siblings bring their kids). My concern is that if we don't say anything, just suck it up, and let them come, then his one sister will do nothing but give us crap (probably, and without exaggeration, for the rest of our lives) about why her kids couldn't come but so-and-so's kids could. That, and really, also, WHO DOES THIS? Why would it ever be ok to say, "gee, I can't make it, I'll just send someone else in my place." WTF? His godparents' daughter's children (this is such a tangential relationship that I'm getting annoyed just writing about it) are 20 and 14 or 15 years old. I'm not necessarily concerned about their behavior; they don't really need to be supervised, and part of me wants to just not deal with it, stick them at the table with their grandparents, and move on. But the other part of me (the part of me that is paying for this wedding) wants to scream, "Under what circumstances do you think this is acceptable? The people who are invited received invitations specifically addressed to them. Your children did not receive an invitation. If you can't make it, I'm sorry to hear that, but it's not alright to just send someone of your choosing in your place." We don't want to upset his godparents, as they are very dear to him, but this is so not ok. I've only met his godparents (and their daughter who did this) once, and I am not comfortable being the person to address this. What do we do??
