Mum's Late

When Jerome's mum is late picking him up, he fantasizes wildly about where she has got to. Has she gone forever, or has she found a new little boy?
 
It's going home time and all the children are leaving. Except for Jerome.
 
Mum is only five minutes late, but to Jerome, it seems like ages and he has all sorts of wild fantasies about what has happened to her. Has she been squashed by an elephant, or has she been held up?
