Officially crazy

It is 2:44 am and I am prowling around the house trying to find the source of the water I swear I hear running from the upstairs bath, but can't hear anywhere else. I have really and truly lost it.

Update: The source was found, apparently our water softener regenerates (whatever that means) at 2:30 in the morning. But, thanks to my prowl, I have been up since 2:31 am anyway. And have I gotten anything useful accomplished? No, not really. Although I did make $26 on eBay today, whooo!
