The key!!! Oh where is the KEY?!?!?!

So, an interesting thing happened after seminary this morning. . . I took Kaili to seminary (scripture class) this morning and settled in to read my book in the car.  Shortly after I had parked, a friend pulled into the parking lot so I walked ten feet to my left and sat in her car where we chatted for the next 40 minutes or so.  It was all-in-all a very pleasant morning in the early spring sunshine.  The kids came out of class and I was to deliver a van load to various destinations, but I could not find the key!  We searched both vehicles, my purse, my pockets, the parking lot etc.  The key just wasn't to be found ANYWHERE.  I didn't even remember pulling it out of the ignition.  With about 8 of us searching, you would think the key would be located in seconds. After about 10 minutes of frantic searching and a phone call to my husband to bring me his copy of the missing article, I finally thought to check my cell phone pocket- what most people refer to as a bra.  To my daughters mortification, that's where I had put it. Everything is good now, the kids have all been delivered and my daughter has been properly embarrassed for the day- - -and it is only 9:30am . . .
what should I do next?
