Who's George?

When Nicholas was around age 4 he had an imaginary friend. He always talked about his friend "George". Rick and I didn't think much of it, other than Nicholas was a little odd (which he still is!). About a year ago, Ellie started talking about George, her friend. We laughed and thought it was a little freaky that our kids had the same imaginary friend. Now for the kicker- Aiden adores his friend "George"! He talks about George all the time. When you ask him questions about George he gets so giddy. He loves talking about him. So- who's George? Do I have a realative named George that's passed on? Maybe there's a spirit that's just really taken a liking to my family. Than again, maybe I've gone some odd kids....they did get my genes!
