 # Instructions
 
-Bob is a lackadaisical teenager. In conversation, his responses are very limited.
+Your task is to determine what Bob will reply to someone when they say something to him or ask him a question.
 
-Bob answers 'Sure.' if you ask him a question, such as "How are you?".
+Bob only ever answers one of five things:
 
-He answers 'Whoa, chill out!' if you YELL AT HIM (in all capitals).
-
-He answers 'Calm down, I know what I'm doing!' if you yell a question at him.
-
-He says 'Fine. Be that way!' if you address him without actually saying
-anything.
-
-He answers 'Whatever.' to anything else.
-
-Bob's conversational partner is a purist when it comes to written communication and always follows normal rules regarding sentence punctuation in English.

- * By adding type hints and enabling strict type checking, code can become
- * easier to read, self-documenting and reduce the number of potential bugs.
- * By default, type declarations are non-strict, which means they will attempt
- * to change the original type to match the type specified by the
- * type-declaration.
- *
- * In other words, if you pass a string to a function requiring a float,
- * it will attempt to convert the string value to a float.
- *
- * To enable strict mode, a single declare directive must be placed at the top
- * of the file.
- * This means that the strictness of typing is configured on a per-file basis.
- * This directive not only affects the type declarations of parameters, but also
- * a function's return type.
- *
- * For more info review the Concept on strict type checking in the PHP track
- * <link>.
- *
- * To disable strict typing, comment out the directive below.
