My parents just got an invite in the mail the other day from their ex-neighbors (they lived next door for probably 10+ years and moved last year.) It concerns their eldest daughter. A daughter my parents have met maybe once or twice over five years ago. My parents aren't even close to the parents at all. My little brother is best friends with their kid, though.
Anywho, the invite says that their wedding is in a couple weeks, but the invite is only for an "open house reception" which will take place several weeks after the actual wedding.
I am so confused. What exactly is an "open house reception?"
