Grandpa and Anthony
Possibly for a picture book or a read aloud book, there is the story of the boy and his two toy plastic motorbike men, Grandpa and Anthony. These two get up to all manner of adventure, but the boy is not at all sure whether or not they are actually alive. Hints are left and he wonders. His mother is certain that they are only toys, but she is a single mum who is far too busy looking after him and his grandpa, the old gentleman. As to the old gentleman, he is quite distant and it may well be that he knows more that he lets on.
