In the story the Big Cat, the ending to me was so closely perfect to the true emotions of what people are feeling in relationships.  Regardless of what someone is verbally saying to another it many times does not reflect what he or she is sincerely feeling.  After he begins to thoroughly digest what he perceives are his wife's feelings of him based on the compilation of the short acting clips that she assembled for him, his mind deciphers what he interprets to be her more accurate opinion of him.  While he rested and or slept the deciphering of his wife's opinion was very distasteful and he naturally felt that he was inadequate and simply something so insignificant that she could easily dismantle him emotionally.
