Kindness is a language the deaf can hear and the blind can see said by a wise man. Showing kindness or giving a helping hand to someone is an investment for the present and future. Most times, we invests in the bank, lands, Crude and various things, BUT THE BEST INVESTMENT IS STILL THE INVESTMENT IN THE LIVES OF PEOPLE.
Let people or their attitude not stop you from give kindness. Let it flow from within.
