What that means: Our washer is not balanced properly, so until I adjust the machine, the washer flips out and becomes unbalanced and galumphs galumphs galumphs. I tend to grab a book to read and just sit atop the washer (instead of dealing with the balance issues). Captain, bless his soul, likes to help me and comes running when he hears the imbalanced washer struggling--and so we both sit atop the washer.
Yesterday while I was at work, the washer was in operation and Captain heard the imbalance and came running to the rescue, standing atop the heaving machine and gentling it with his weight, just a bit.
