Use your heart and it will tell you how. What do you do when a kid pees in their pants/shorts. Your heart tells you certain things. Assuming you have compassion in your heart, follow your instincts. Leave the head alone for a while. Folks are usually unhappy mostly due to ignorance. Without losing the "human" touch get the pill of knowledge into them, if possible. If you least worry about "I" and only think of "them", purely with the intention of being an instrument/servant of the Divine in rendering help, compassion finds a way of manifesting itself. :)
