Hi, Q1: The goal is to return the current object with 'self'.
When, you try in irb => 'a' && 'b', Ruby returns you 'b', because is the last non nil object but when the password comparaison failed, it the comparaison value which is returned, thus 'false'. Q2: According to my interpretation, there is none validations on the current object. Best regards.
