Quote of the day
Those who grieve frequently find themselves alone. Missed is the laughter of children, the commotion of teenagers, and the tender, loving concern of a departed companion. The clock ticks more loudly, time passes more slowly, and four walls can indeed a prison make. I extol those who, with loving care and compassionate concern, feed the hungry, clothe the naked, and house the homeless. He who notes the sparrow's fall will not be unmindful of such service.
