We just received the sad news that my FI's uncle is being placed on hospice care with only palliative care from here on out. I'm sending out the invitations this week, and I have no idea how to address this one for his aunt and uncle, given that there's a very good chance he'll have passed by the time they receive the invitation in the mail. I also don't want them to be the only ones who don't receive their invitation when the others do (they're a close-knit family).
I just don't want to cause any more heartache for his aunt. Any advice?
