Hi,
How about this one, Not all dishes will fit in the dishwasher standing up (neither will they get clean in any position, especially if the dispenser gets blocked).
Also, there's no easy defense when your sister(s) say, 'It's his' (corollary to Moms believe girls more than boys).
Also, a basketball can bounce high enough from 30 feet away to break a window (yes, I learned that one from experience, too).
Or, records do not make good frisbees.
P.S. -- Three of us used to drive Mom crazy by singing half-steps apart. It worked great because one of my sisters had perfect pitch and would just sing a half-step away from whichever note me or my brother chose, and then the third would find the other half-step.
