Never happy with their lot.. always have something to complain about. You know the ones... they get taken for a wonderful day out, and yet complain about the few spots of rain they got.. The would win the lottery and complain about having to pay taxes or having to go all the way across town to pick up the cheque.
These people need to be given special glasses that let's them see the good things in life. We'll call them posi-specs.
