I had posted something earlier about connecting with Facebook & stuff, and then that you will discover people you knew have some big issues in their lives.
I thought when something came around about a little boy with cancer who was requesting Christmas cards that it was someone personally known to one of my friends. Turns out they were just spreading the word about this little guy.
So if you would like to contribute to the little boy's wish, here's the info to send a card:
1141 Fountain View Circle
South Lyon, MI 48178
It's a valid request - here's the snopes post (and you can even check his carepages if you'd like).
