It is often that a cow does not take after its breed. A hound's food is in its legs. The day will come when the cow will have use for her tail. When fire is applied to a stone it cracks. Need teaches a plan.
Necessity is the mother of invention.
Lack of resource has hanged many a person. Time is a great story teller. There is no need like the lack of a friend. Nodding the head does not row the boat. A heavy purse makes a light heart.
