Does anyone else feel like they are having the world's greatest birthday party when you see things checkedoff the registry?

...a few of members of my FI's family have not quite figured out that we registered for what we specifically want, and not random things they decide we need (without receipts). My dance troupe talked me off the ledge yesterday with tales from their bridal showers and things they ended up returning or regifting. Has anyone else started experiencing odd registry behaviors from friends or family?
