So he probably had been sleeping for a while after being falling-down-drunk and abruptly awakened. That sucks sucks sucks.
An acquaintance was arrested for being drunk in public and also not having enough money to pay his taxi driver. I snagged his photo off the internet - Johnson County Kansas posts every single mug-shot online...and they make the inmates where a gray cloth for the photo, so its just their face and no clothing, logos, etc.
I sent the photo to the guy - he replied back ‘What is that gray thing I’m wearing’. He had no memory of even being photographed.
