I have a friend from college that I haven't spoken to in about a year. We're friends on FB and I'm pretty sure she lives out-of-state now. Yesterday, she wrote on my wall, "So, when is the wedding? I just want to make sure I don't miss it.

" I haven't been posting wedding-related updates on FB, but I do get an occasional wall post from a family member (who is invited) that I'm sure this girl can see. I just don't know to respond to this - we haven't spoken in a year and shouldn't she just wait and see if she receives an invite? I'm also wondering if maybe she knows she won't be invited, but wants to send a gift? That's not what the comment sounds like though. Any advice on how to respond to this?
