Never Milk That First Cow

When my mother got married, my grandmother gave her this advice--never milk that first cow.  My mother relayed the message to me when I got married.  The idea is to be careful before offering goods and services that could become an expected norm later.  

I think of their wise advice often.  I wish proponents of big government would consider it before obligating future generations to expensive and expansive social experimentation not addressed in the Constitution--especially when our grandchildren and those yet to be born are the ones who will be obligated to do the milking.
