I need 5 minutes peace.

I've been at my parents house with the children for three days now. It seems that whatever I tell the children not to do they do it faster, louder and with more annoying whine that ever. I think I'm going to go insane. I'm sure they are praying for Friday so they can wave good-bye from the front porch and then run inside and enjoy the quiet. I just double locked myself in the bathroom so I could enjoy 10 minutes of peace - I needed to wash my hair too, but it was mainly for the quiet. Seriously.
