And I knew too well the loneliness that clamps around one's heart when loved ones have passed on before. To have that companionship, the comfort of someone being at home for you for years, and then suddenly not to have it anymore--well, every day can seem darker after that, and the vise clutches tighter in your chest every night you spend in a lonely bed. Unless you find someone to spend some time with (and that time is sunlight, golden minutes when you forget you're alone), that vise will eventually crush your heart.
