Separating from the flock
There is a reason why a lamb gets separated from a flock. The flock will be eating on a particular pasture and a lamb will take a fancy to graze just off to the edge of the field. So the lamb takes a little nibble of this grass. Then he moves just ever so slightly further from the edge and takes another little nibble, then just a bit further and another nibble.
Each little nibble of grass takes the lamb further and further from the flock. After a while, having eaten enough grass, the lamb pokes his head up and notices that the flock has left him. B-A-A-A-A-A! The lamb wails. How could his flock have left him? We begin slipping when we stop paying attention to our flock. My group will not leave me: I will leave my group. After a while I, too, could end up wailing for help just like the little lamb.
