Who does Lencho think has taken the rest of the money? What is the irony in the situation? [Remember that the irony of a situation is an unexpected aspect of it. An ironic situation is strange or amusing because it is the opposite of what is expected.]
Lencho thought that the post office employees had taken the rest of the money. The irony of the situation was that the employees whom he called a “bunch of crooks” and suspected of taking some of the money were the same people who had contributed and sent him the money in the first place.
