What if someone you loved and lost wrote to you years after their death? It's a question one man lived this week.
His dad wrote: "Hopefully by now you have adjusted well enough to life without the old man and you have managed to help your mother adjust. ... The first thing I want to say is just how proud I am."
The father used FutureMe, a website that lets you send your future self an email. Registered users can send future emails to others, too. Several other sites, like EmailFromDeath and Afternote, also let you send posthumous letters to loved ones.
