Causing Unnecessary Panic

I came home last night from work and pulled into the driveway.  Upon my arrival, I noticed the side door to my wife's van was opened.  My initial thought was that someone had broken into the van.  A closer look proved me wrong.  It looked as if everything was still in the vehicle.  I went inside the house to ask my wife if she had been to the van recently.  Her response was that she had not been outside for the past 6 hours.  I told her she want to check the can cause the side door was wide open.  She rolled over and went back to sleep.  I hate getting myself worked up over nothing.  I guess I need to take some advice from my wife and just not give a fuck about causing unnecessary panic.
