How to tell if someone is getting a divorce without actually asking them

Now that I have so many friends on Facebook, some of whom I have actually met in the flesh, I am seeing more of a trend among divorcees. I first noticed this trend when I was still in the library biz, because so many librarians are women. But I notice it more now that I have so many friends all over the country.

No-one wants to flat out inform their friends, one by one, that a marriage is over. But there is a tell which shrewd observer will pick up on 90 percent of the time. Say a woman's birth name was Susan Smith, and she married a man called Andrews a long time ago. She got tired of Mr Andrews, threw him out, and is getting a divorce. But she doesn't want to give up the Andrews surname right away, maybe because they have children. So she calls herself Susan Smith Andrews, or Susan Smith-Andrews.

After a while she doesn't want to be called Andrews any more. She wants a whole new life. Maybe she wants to date, or to meet new people. So she reverts to Susan Smith.

Usually, about this time, she buys a new car.
