O ~ Old Maid

In the community I grew up in, the average age for a girl to get married was 19½.

If they weren't in a serious courtship by the age of twenty-one, their chances of ever getting married dropped dramatically, and most resigned themselves to the fact that they would most likely be an old maid.

Old maids didn't move out of their parent's homes. Instead they would be the ones then caring for the aging parents once that was necessary, even moving into a dawdy haus with them.
