Do I have a screw loose?

There are some things in life with kids that are unexpected.  I think we all accept that, and roll with it, at least I try to.  Then there are those events that not only take me completely by surprise, but days and weeks later, I find myself still trying to wrap my mind around the reason why; to no avail.  The one person who can explain it and help me to understand is Kid 5, and she isn't talking; at least about what I am asking - she talks about everything else.

It went down on a Monday night.  Daddy had a late softball game, so after dinner everyone got ready for bed as Daddy left for softball.  Kid 4 wanted to watch TV with me in bed for a while as Kid 5 bounced around the bedroom.  Kid 4 accidentally spilled water on the bed just as we settled down.  

With a huge sigh of exasperation, I got out of bed to strip the sheets from the bed so I could put them in the dryer.  As I began to pull the comforter from the bed, which is a white quilt, I noticed a bunch of tiny screws on the foot of the bed.  I had an errant thought that Daddy had bough a new piece of softball equipment that screwed into the packaging  and that he had left the screws on the bed.  I absently gathered the screws and placed them on the dresser, more concerned about the fact I now have to wait for the sheets to dry before I can get back into bed.  

As I dragged the sheets down the hall to the laundry room, which is next to Kid 4 and 5's bedroom, I am tired and annoyed.  I stuffed the sheets into the dryer and turned it on.  As I left the laundry room I reached to turn the hall lights off.  As I did this, I noticed that the screws had been removed from the light-switch plate.  All six screws.  

I realized that the screws I had found on my bed belonged to this light-switch plate.  Shaking my head in disbelief, I walked to my bedroom, gathered the screws, and found a screwdriver after a bit of a search.  I walked back to the light-switch plate and began to put the screws back in.  

As I began to place the second screw into the plate, to my frustration, I dropped it onto the carpet - where I found six more screws.  At first I did not understand what I was seeing.  I was confused.  If the screws to this light-switch were on the floor, where did the screws in my hand come from?  I turned around and checked the light-switch plate across the room.  Lo and behold, there were six empty screw holes, and on the ground below were six more screws.  So I had 18 screws and 12 screw holes.  After placing  12 of the screws back where they belonged, I went on a search to find the light-switch plate to which the last six screws belonged.  I found it in the hallway next to my bedroom.  

As I placed those last six screws back where they belonged, my only thought was that Kid 5 did it.  Who else would?  Certainly not I.  Daddy wouldn't know which type of screwdriver to use.  It would never occur to Kid 4 to do something like that - he's too busy building Legos and watching Star Wars.  Kid 3 was not home, so there you have it.  Kid 5 must be the culprit.  

I asked Kid 4 and 5 who took the screws out of the light-switch plate.  Both denied it, surprise surprise.  But Kid 5's denial was not genuine.  It was an attempt to stay out of trouble.  Too tired for confrontation, I took my sheets out of the dryer, fixed the bed, and waited for Daddy to come home

It wasn't until the next morning I realized that there were more screws missing in a light-switch plate downstairs by the kitchen...to date, I still haven't found those screws.
