Creepy Doorbell Ring

The kids and I have just been sitting around this evening them mostly playing and me blogging. When all of sudden the doorbell rings. Which is odd because it never rings unless we are expecting someone or my mother in law comes over. So I look out the window and their is no car in driveway so I am like WTH? And I finally say "Who is it?" and of course no one says anything which just freaks me out. So I tell my sons to lock themselves in the bathroom. And I sneak out the back-door to walk around the house to see if anyone is there. Well no one is there but I am just freaked out because that is weird. Maybe it was just some kids playing a joke, which I can live with because I was once a kid too.
