Or rather, that I assumed we weren't invited to, since we never received a save the date or invitation. We've seen them on the fridges of mutual friends for months/weeks and figured that we just weren't invited, and it wasn't a big deal... but then FH gets a nice message asking him to be a groomsman. We know they have our address because a mutual friend told us that he asked for it months ago. The whole thing just seems so weird to me.
Has anyone else experienced anything like this? FH already said yes, so I guess that's happening.
