Black Cloud?

Oddly enough the last two Saturdays in a row I have had a horrible night at work. Some people in our unit get pegged as "black clouds" because we all know bad things happen when they are involved. It's extra specially bad when these folks are in charge. I've never had this particular term associated with me, and I really hope it does not follow me around for much longer. All I can say is, better Saturday night than Friday :)
