Help them exercise their creativity. Provide them with clay, paints, fabric, glitter glue, sketchbooks, pens of magnificent and splendid color. Try Daniel Smith or the U. Bookstore for great selections.
Time. Either spend some time with them (take them out for lunch, dinner, to the zoo, up in a balloon, out for coffee and chat, on a cruise) or save them some time (sign them up for a delivery service, offer to baby-sit, help out with errands or household work). Or offer them proof-reading/copy-editing time.
