Are they feeling blue, in a blue mood, and ready to sing out some good old-fashioned blues? There's something about the word blue that conveys those familiar symptoms: a heavy heart, a depressed spirit, and low energy. Gifts for those experiencing the blues range from practical gifts, such as a sunlight lamp, to more luxurious gifts such as chocolate therapy and bath products. Whatever you choose, they'll know you're thinking of them during a particularly blue period in their lives.
