sleeplessness

It is not unusual to find me asleep in chair around 8 or 9 on a Sat. evening but when I HAVE to go to bed early, I'm as wide awake as can be. Why is that? And why do people leave their porch light on all night? especially in this neighborhood? not exactly a high crime part of town-at least as far as I know, will need to check the police blotter in the Farragut weekly news this week. Why do people leave their dogs out all night so they can bark and wake me up? And why does my Green Day addicted son need to put his CD on repeat every night? So I was up at 3.30 a.m. for inventory at one of the stores, a necessary evil but I HATE inventory. The only one in my 9 million years of retail that I managed to get out of was the one when I totaled my car at 7 months of pregnancy and had to spend 4 days in the hospital, a little dramatic perhaps but I did get out of that inventory..Anyway I am tired and a little cranky so I think it may be bed time!
