Your family takes a trip and your mom forgets to pack your clothes.
So, all weekend long you get to wear your jammie shirt (which your mom did remember), your sisters shorts (the ones without the pink flowers) and socks (which unfortunately do have pink but are fortunately covered up by your shoes).
In defense of your mom though…you were taking a nap while your mom packed the bags. And like any smart mom of multiple, small children she values her quiet hour of sanity during nap time. So of course she would never dream of waking you up during your nap to get your clothes out of your dresser.
