My sister-in-law (married to my brother) likes to be alone, enjoys her days out in the middle of nowhere while my brother is at work. But I don't know that anyone can be alone, alone; not have special friends, etc.

My aunt never married; she'll be 87 in April. But I don't think of her as having been alone. She lived and still lives a full life with lots of friends and church connections and work and relatives and stuff.
