“ look for a long time at what pleases you, and longer still at what pains you... ”
It's so curious: one can resist tears and 'behave' very well in the hardest hours of grief. But then someone makes you a friendly sign behind a window, or one notices that a flower that was in bud only yesterday has suddenly blossomed, or a letter slips from a drawer... and everything collapses.
~ Colette
If he's getting married, he's not longer interesting.
You will do foolish things, but do them with enthusiasm.
No one asked you to be happy. Get to work.
