Have you practice a litle love today? To your loved ones perhaps? Your parrents, your spouse, your children, your neighbours, or even your enemy? Here is a short tip on how to love them - Love is patient, love is kind. It is not jealous, is not pompous, it is not inflated, it is not rude, it does not seek its own interests, it is not quick-tempered, it does not brood over injury, it does not rejoice over wrongdoing but rejoices with the truth. It bears all things, believes all things, hopes all things, endures all things. So these three remain ... faith, hope, and love; but the greatest of these is love.
