groper lips speak vowels fall forth chipped pearls of wisdom skitter about the ground seeking purchase in mud pockets finding only dry sand and bitter salt
******* in salt for forty years can do that curdle the cream of wisdom leaving just the sour to spew out
but if clever you can sift the detrius and make cheesecake with chipped pearls on top
there is a point in some academic's life...when the tipping point is met and they just teach by rote....it is then up to the students to glean what wisdom they can...at least until some one gives the churlish academic a slap upside the head.....we at present have this situation in my dept( no it is not me) ....time to get my slapping gloves out....
