            | Letter 1 Your article (November)   mentioned a doctor's visit for "heat and compression"treatment. I   bought an inexpensive microwavable moist-heat eye compress online and use it   for several minutes at bedtime to help open the oil glands. Plus,the warmth   and ritual help me relax and fall asleep. No more messy washcloth compresses   for me! ——Julie   Evans Minneapolis,   Minnesota | Letter 2 The Quality Inn in Kodak, Tennessee, turning into a shelter during a historic winter storm   showed so much kindness that I read the story twice (November). For   Sean Patel to open his hotel to locals in need during the storm and power   outage, at Christmastime and for just $25 (the lowest price the corporate   regulations would allow), was priceless. The town is a better place because   of Patel and his staff. ——Annette Wolfe Shelton, Connecticut | 
        
            | Letter 3 You suggested using toothpicks to   raise a pot lid and prevent the pot from boiling over (October). I   prevent boilovers by just laying a wooden spoon over the open pot. The spoon   will pop most of the bubbles on contact-hasn't failed me yet! ——Pam   Snellgrove LaGrange,   Georgia | Letter 4 The story about a snorkeler, Carter Viss,who lost his arm   after getting hit by a speedboat (October)— and then forgiving the   driver— was among the most compelling I've ever read. Here was a story of   health and loss, sea and shore,healing and the hope to endure out of the   darkness into the light. Simply marvelous! ——Leander Jones Northport, Alabama |
