"If a tree falls in a forest and no one is around to hear it, does it make a sound?"

I am working the graveyard shift of late, a matter of necessity not of choice, and my co worker and I are the only ones in the office for the night. She was ill most of the week, and Thursday night into Friday I worked all by my lonesome, hence no pics. I was in a Buchanan modern hunting kilt but the question arose in my mind if a kiltie wears a kilt on Kilted Friday and no one is there to see it did it really happen?
