In the first book he written (a child called it) he mentions that his mothers starved him for years, but earlier in the chapter he says that he has the same menu that his mother packs for two years.

Another slip up is in his second book he written where earlier in the chapter he writes how he didnt have a bike and never owned one, but in the more later chapters he writes about how his mother and brothers came in with his bike which he was never allowed to ride becuase he was on punishment.
