+# Instructions
+
+Your task is to determine what Bob will reply to someone when they say something to him or ask him a question.
+
+Bob only ever answers one of five things:
+
+- **"Sure."**
+  This is his response if you ask him a question, such as "How are you?"
+  The convention used for questions is that it ends with a question mark.
+- **"Whoa, chill out!"**
+  This is his answer if you YELL AT HIM.
+  The convention used for yelling is ALL CAPITAL LETTERS.
+- **"Calm down, I know what I'm doing!"**
+  This is what he says if you yell a question at him.
+- **"Fine. Be that way!"**
+  This is how he responds to silence.
+  The convention used for silence is nothing, or various combinations of whitespace characters.
+- **"Whatever."**
+  This is what he answers to anything else.

+# Introduction
+
+Bob is a [lackadaisical][] teenager.
+He likes to think that he's very cool.
+And he definitely doesn't get excited about things.
+That wouldn't be cool.
+
+When people talk to him, his responses are pretty limited.
