Stephen is keeping something from me. We have been married for 49 years and never kept secrets from each other but I can't help but notice how his behavior towards me has changed. It's as though I am a ticking time bomb that sets him on edge, has him waiting for an explosion. The children, who usually visit only for holiday get-togethers and birthday celebrations, have been around the house more in the past week than they have in the past five years. They've been uncharacteristically caring. I don't understand. Is there something wrong with... what was I saying?
