From Maria's diary, one night when she lacked the courage to go out,

to live or to continue waiting for the phone call that never came:

(...)

The roller coaster is my life; life is a fast, dizzing game;

life is a parachute jump; it's taking chances, falling over and getting up again;

it's mountaineering; it's wanting to get to the very top of yourself

and to feel angry and dissatisfied when you don't manage it.
