Everything you need to know to get by in life you learn in Kindergarten... patience, manners, respect, self control, sharing, taking turns, picking up your mess, interacting and communicating... etc. No, we don't learn everything in Kindergarten we just learn everything we need to know to get by.  Utilizing the concepts of what we do learn in different ways is how we become individuals of our own.  If you think about it, each of us is born to this world knowing nothing but the voice of our mother.  From the time we breathe our first breathe until the time we take our last, we are learning.  Depending on the influences around us is how our personalities are created.  Something that people neglect to see which causes them to be very critical is that from the time we are born it's inevitable that our bodies grow.  We have no control over that. We have no way to slow down or stop the process in which we grow into an adult body.  But, our knowledge and mental status grow by influence.  We can't expect anyone to know anything that they weren't taught. Many people are not influenced properly as they are left to raise themselves if a parent passes away or a single parent has to work.  Furthermore, so many people are presenting as adults though reacting and expressing themselves like children.
