Malis Mala succedunt.

A succession of misfortunes, one following another, as happens to some ill-starred persons, who have no sooner learned to bear one trouble, but another falls upon them. Hence it has been said,

Fortuna obesse nulli contenta est semel.

Misfortune seldom comes single. The Spaniards therefore say, Ben vengas si vengas solo, you are welcome if you come alone.
