Just boring for the most part....................so I am led to believe. Not personal experience you understand.
I was a volunteer on a medical study once and the guy in the same group as me had spent time in nick. 18 months or so. He said it was kind of like being on the study we were doing, just laid about on the beds talking and reading and maybe the odd game of pool thrown in.
I don't remember what he did time for but when we were watching a footie match on television one night he did say casually................''see that refeshments stand? I smashed that up a couple of years ago with my mates''
Quite proud of it in fact.
You might imagine he was a knuckle dragging, tattooed hard case, but in fact he was well dressed, articulate, polite kind of bloke, married with 3 kids and a good job.
He did say he thought nothing of breaking into a house if the chance arose justifying it by saying, ...................'well, any stuff will be insured''
His words didn't fit the bloke, it seemed odd.
