Happy birthday to me

Rico says it's still amazing, given everything that's happened in the last five years, that he got to be this old, but his friends remember, which is nice:

His cousin Susan and her husband, to be expected, but appreciated.
His old friend Hansford, a thoughtful gesture, and appreciated.
His dentist Alan, a computer-generated response based on his client database, but appreciated anyway.
But birthday greetings (even using his cowboy alias) from The Authentic Campaigner? Amazing...
