Cows and books

Obligingly they dip their heads to feed and chew
Their bodies automatically filling their bellies
Their hunger is insatiable
They eat, chew, digest and absorb
Similarly, we lower our heads to our books
Drinking in knowledge and wisdom
Insatiable is our hunger
We cannot ever attain enough to be fill
We eat, chew, digest and absorb
We are like the cows
They eat
We eat
They must
We must
We are the same, but not at all...
