" Two people who have loved each for long enough eventually seem to stop touching each other consciously, it becomes something instinctive; when they meet between the hall and kitchen, their bodies somehow find each other. When they walk through a door, her hand ends up in his as if by accident. Tiny collisions, every day, all the time. Impossible to construct. So when they disappear, no one knows why, but suddenly two people are living parallel lives instead of together. "
― Fredrik Backman , Us Against You (Beartown, #2)
