I had to go to a work event today (I usually don't work Fridays) and so I got my sister to babysit. I came home half an hour ago to find her absolutely hammered and my brother who she clearly brought with passed out on the floor. They've drunk 3 bottles of wine and some amaretto by the looks of it. DD has just been playing with herself in her room whilst they've been getting sloshed and goodness know what would have happened had dd had a problem.
