Who never lost a sock, leaving only a celibate sock in the drawer that you're reluctant to throw in the garbage? I've lost many socks, leaving quantities of celibate. Usually, I use blue socks, sometimes with different patterns, but they are still usable with other blue socks to form a new pair.
But THOSE socks were forest green, wool socks, given by my mother, and I LOVED them. So I was all worried that time when I came back from doing my laundry, and found only one of them! I kept it in my drawer for a few MONTHS.
Until one day my mother have been doing some laundry, and she sent me to pick up the clothes on the clothesline, and there it was, between two towels! I was WTF??? I picked it, bringed it back inside, and checked in my drawer: his twin was still there!
I never knew where this sock went for months. Perhaps was it stuck in the washing machine. Perhaps my (late) mother found it and played me a joke.
