Vexation
Your children were vexation to your youth.
Shakespeare.
Vexations may be petty, but they are vexations still.
Montaigne.
There are two things which will make us happy in this life, if we attend to them. The first is, never to vex ourselves about what we cannot help; and the second, never to vex ourselves about what we can help.
Chatfield.
