1 star for me. By buying it, I expected some funny ideas to the world *** em, it is the case to say ... But 3/4 of what is found in it are things or 'book we do not need to think about: park straddling two parking spaces on the bus press the "stop requested" button without intending to go down, the inverse of a remote control batteries, and j 'on the way. No interest for me!
