Yes, a long time joke to all - we put both socks in the washer and by the time we get them out of the dryer, 1 sock to the pair has mysteriously vanished!
One day while at a street fair when Brady was 6 and Keaton was 5 and we came across this 'toy':
So, anyway I use this device for grabbing the laundry that falls behind the washer and dryer and find MANY missing socks and boxers and mittens and t-shirts - it's great! It is over 10 years old and still going strong - this is an amazing tool, probably one of my favorites!
So, socks do not really disappear, they're just hiding!
