As I write this, I sit in Heathrow airport in London, having just arrived from Chicago (this will be posted later). I’m on the first leg of a journey to meet the senders of messages in bottles, and hopefully to make new friends. I’m surrounded by strangers, and yet, I can’t shake the feeling that there must be invisible connections between us we are simply not aware of. Maybe someone near me has visited my hometown, or maybe they know one of my friends. Heck, I may actually know someone here!
