  3. Cathy, I’m so sorry. You and Tom were a big part of our lives for years, and I have great memories of those days. I’m also sorry we lost touch. Life has a habit of going on while we are busy attending to unimportant details. I so much appreciated the call from Ingrid today. It was very thoughtful of her in a very busy time.
