My husband and I got invited to my friend's older brother's wedding "open house." It is at a church, and apparently they're getting married in another state the week prior, then coming back for this open house. The only thing is, we were invited on Facebook to the event, by the Mom, and she only listed their registries (no other details). I'm not sure if this is an actual reception or if it's more of a wedding shower? Does anyone have a guess? If it's a shower we don't feel close enough to them to attend. Has anyone been invited to one of these before?
