Mr. Kuus's family has this thing they do where when one of them (or unfortunately us) throws a party, they all think they're cohosts who need to come early, "help", and stay in the kitchen and "help" for the majority of the party. This help mostly consists of hovering a scant six inches away from the real hosts and asking repeatedly what they can do, then apologizing profusely when the answer is "get out of the way" before starting the process all over again.
Drives me up a damn wall. They come right back when you take them by the shoulders and escort them out, too.
