Strays is what a writer I recently read calls those who, for one reason or another, and despite whatever they might have wanted earlier in life, never really become a part of life, not in the way most people do. They may have serious relationships, they may have friends, even a sizable circle, they may spend large portions of their time in the company of others. But they never marry and they never have children. On holidays, they join some family or other group. This goes on year after year, until they finally find it in themselves to admit that they'd really rather just stay home.
