Out early so as not to wake the house

Stressed, for no reason what-so-ever and awake at 4 am.
I decide to sneak out for a coffee because if I'm moving around the house, making a drink etc, the dogs will wake up and then wake up everyone else.

At least with coffee and my book, I can relax and watch the other insomniacs come in for food and a drink.
Eventually got tired again around 7 am, went home and caught a few more hours of sleep.
