// Filtering The Children (part 3)
// Yet again, Santa has made a request to change the children filtering code. This time he just sent an email to the entire engineering team (which is absolutely not the process, but since Santa is sometimes a bit difficult to communicate with, no one has yet had the courage to tell him). Here's the contents of the email.
// POST /sendmail HTTP/1.1
// Host: mail.hohoholdings.com
// Content-Type: text/plain; charset=utf-8
// Content-Length: 420
// From: kris.kringle@hohoholdings.com
// To: engineering@hohoholdings.com
// Subject: Code Changes Needed
// Hello beloved team!
// Looks like we need some changes to the code again!
// 1. there are sometimes naughty kids in the same list
// 1. turns out I don't actually need to see the nice children in the list, after all
// 1. my golf game ran late this morning.. so since the other two changes were quick to implement, I'm sure this will be just as fast, right?!
// - Kris Kringle
//   "at Santa's workshop, we value loyalty over all else"
// Wow. What a pointless email. For once, calling a meeting would have been better.
// Good thing we got some experience reading the tests because this email may as well have said "do work. thanks." (lol).
// Off to the tests to see how this is actually supposed to work!
