I have a married cousin with a young daughter. FI and I decided to invite very few kids to our wedding (basically just kids involved in the wedding). Cousin's daughter is not in the wedding, not technically invited. Cousin is very likely to assume her daughter is invited (I won't bore you with details unless you really don't believe me but for the sake of brevity, trust me).
So we sent our invites about 3 weeks ago.
Today I got a text from her basically saying, "Hey! I still haven't gotten your invitation in the mail, but we are coming! We're invited right?" She is, and she got the Save-the-date addressed to her. But, yikes, do I need to tell her the kid is technically not invited? I know it's not proper to do that, but she lives 6 hours away and while they won't be buying flights, it is a full weekend away for them. On the other hand, truth be told, if her daughter came to our wedding I really wouldn't mind, but FI would be upset.
Should I just write back and say, "Yep! You and H are invited!" and see where that gets me? Anyone have a better idea? So much for that properly addressed envelope, stupid post office.
