Witnessing History

Osama Bin Laden was killed yesterday. Today I am watching the Today Show on my Roku.  It is amazing to me that this is something that will (hopefully) be written about in history books, and I am sitting and watching it right now.  My kids are too little to "get" that anything is going on, but it makes me wonder, what will you tell your kids?  It isn't really something that can be explained without some backstory I would think.  But it does put things in perspective a bit to be a part of history.  Someday I can tell my grandkids I remember when.  Just the thought of having grandchildren is an overwhelming one though.  So, how are you going to explain this to your children?
