AS BAD AS CHALK ON BLACKBOARD!!

     The kitchen where I grew up was huge with this single free standing sink with legs, single basin, and built in drainboard to one side that sat  at the north end of the room. It served all our needs including a porcelain round pan to  wash your hands. 

      If the bottom of the basin wasn't keep perfectly clean, grit, dirt, and sand bits would accumulate. Then, when that pan would slide around, it would make this awful screeching sound that could "send you up a wall!" Some things stay with you forever, even sounds!
