“We mustn't keep meeting like this. Communications between the people of the moon and earth is forbidden...it is the way of the gods...we mustn't fall in love...but its already too late......”

“We have to live like people in a web of knives, we mustn't reach out our hands or we get them gashed.”

“AND IF WE ARE TO STRIVE FOR A BETTER FUTURE, MUSTN'T WE BE FAMILIAR AND RECONCILED WITH OUR PAST?”

“If you and I are to live religious lives, it mustn't be that we talk a lot about religion, but that our manner of life is different. It is my belief that only if you try to be helpful to other people will you in the end find your way to God.”

“Oh, my dear boy, one mustn't expect gratitude. It's a thing that no one has a right to. After all, you do good because it gives you pleasure. It's the purest form of happiness there is. To expect thanks for it is really asking too much. If you get it, well, it's like a bonus on shares on which you've already received a dividend; it's grand, but you mustn't look upon it as your due.[The back of beyond]”

“... we absolutely mustn't forget it. We mustn't forget old people with their rotten bodies, old people who are so close to death, something that young people don't want to think about (so it is to retirement homes that they entrust the care of accompanying their parents to the threshold, with no fuss or bother). And where's the joy in these final hours they ought to be making the most of? They're spent in boredom and bitterness, endlessly revisiting memories. We mustn't forget that our bodies decline, friends die, everyone forgets about us, and the end is solitude. Nor must we forget that these old people were young once, that a lifespan is pathetically short, that one day you're twenty and the next day you're eighty.”
