Alexandra Marinina. Spring for the traps (№ 129091)

I can't regret what has been and gone. I can somehow relate to the past, good or bad, but regret is stupid. Regret is unhelpful, out of a sense of regret can not create anything useful. To the past should be treated with gratitude, because it gave me some experience from which I learn lessons and draw conclusions. Even if the experience is very bitter and heavy, it will still learn, get smarter, and for that he thanks a lot.
