She strikes again

When will I learn that Ally needs constant supervision? I was downstairs for 2 minutes throwing in a load of laundry (I know cleaning again, I said I wasn't going to do it). I come upstairs to a very guilty Ally saying "sorry mommy". She had gotten a pair of scissors and cut her necklace. I guess she wanted to hide the evidence so she cut up my sheets and was putting all the beads through the hole in the sheets. Agh, are you kidding me. Anyone seen a good sale on sheets?
