Don't judge, be a friend. Offer to help, and make your offers specific. Don't push but offer. Respect their own private space and private time. Respond to them body, mind and spirit.
Balance is of the essence here.
Trust the other to lead you. Radiate genuine hope. Journey with them, holding sensitively to their hope until they can hold it for themselves. Authentic hope if you please. Carry the other in your heart and soul.
