Earlier this afternoon, I too received such a letter. At first, I had actually believed it... But now I know of the truth, which I must say: 'Tis quite the disappointment. Sadly, I've already sent back the letter as asked. I suppose that means I'll be hearing from him again (Woohoo). As for any future receivers of such a letter, take a good look at the address. If the address reads as the following, then I recommend that you take it to the police or the post-office and have as much done as possible to stop this:
3357 H. Southpark Place
Grove City, OH 43123
As for anyone who'd rather believe his lies, you have as much of my sympathy as I have regrets of this situation... And all should always keep these words in mind: The meaning of life is that which motivates one to have a life. In other words: Focus on the things in life that make you happy, and think nothing of these letters.
