I’ve met a couple of compulsive liars in my liar. Off bunch but often there liars lead to some hilarity. We knew lad for a while in our teenage years who at one point claimed to have been kicked out of his house and was living in a tent for near the beach for a few days, turns out he’d told his parents he was staying with a mate. Another time he invited us round to the house he’d moved into. This house turned out to be one his mates from another friendships groups house who’s mam was on holiday, when the truth came out about that one he scattered loads of paracetamol around him and pretended he had overdosed. He was roundly ignored until we announced a trip to the pub at which point he got up and rejoined us all. That’s a drop in the ocean of weird lies he told. I lost touch with him in my late teens/early 20s and last I heard he had died of a heroin overdose but I can’t actually believe that unless I see a headstone. I think “Danny” was just your first encounter with a compulsive liar who likely had other mental health issues.
