Knowing me, I'd have wasted day one playing games, drinking tea and eating toast, only realising the note was there when the wife didn't come home at her usual time.
After that I'd probably play games til whenever, have an epic lie in the next day and then go absolutely mental, doing things you wouldn't normally be able to do, like wandering around Sainsburys absolutely starkers.
I'd also go into the City Centre, and feel the absolute perfect bliss of being able to walk anywhere I like without people walking really slow in front of me, or being harranged by people with clipboards, or lucky heather, or whatever.
At the end of Day the I'd watch the sun go down in the countryside, happy that I'd wake up the next day with my wife in bed beside me and the knowledge that everything was back to normal.
