Nature has many laws that hold fast and true.
For example, a baby ape will always grow-up to be an ape; likewise, a baby baboon will become an adult baboon.
A baby pig will mature into a full grown pig.
A baby jackass will always become a jackass.
A puppy quickly matures into a dog;
a mongrel pup develops into a cur.
Yet oddly enough, women say a young man may grow-up to be any one of these.
