We Church Ladies tend to be big fans of the Corporal Works of Mercy (go figure). Personally, I like them so much that I'll sometimes expand the list a little. After reading this challenge, I'm tempted to add "Send Valentines to the lonely" to my canon of tasks. Go read the post, and I guarantee someone will spring to mind immediately. Dash off a little heartfelt note - along with, if appropriate, some chocolate - and brighten someone's day.
