This will not be a funny book. I cannot tell jokes because I do not understand them. (13.1)
Siobhan also says that if you close your mouth and breathe out loudly through your noise it can mean that you are relaxed, or that you are bored, or that you are angry and it all depends on how much air comes out of your noise and how fast and what shape your mouth is when you do it and how you are sitting and what you said just before and hundreds of other things which are too complicated to work out in a few seconds. (29.4)
And this is because when people tell you what to do it is usually confusing and does not make sense.
For example, people often say "Be quiet," but they don't tell you how long to be quiet for. Or you see a sign which says KEEP OFF THE GRASS but it should say KEEP OFF THE GRASS AROUND THIS SIGN or KEEP OFF ALL THE GRASS IN THIS PARK because there is lots of grass you are allowed to walk on. (59.3-4)
