Which refusal strategy does Devon utilize in the scenario above?

If other readers feel that Tom goes too far in his pranks, I do not agree with them. In fact, I think Tom's pranks are normal and does not go too far at all. I can understand that Tom is a very young and immature lad, and these pranks are fathomable enough judging from his age and upbringing. 

If I were to put my shoes in those people affected by his jokes, then of course I'd be somehow irritated. However, I would consider his jokes as being his nature as a boy, so I'll be a good sport about it. Although I understand Tom, I will find a way to outwit him and be more wary about what could happen when it involves him.
