My dad is sadly like this. I'm very close to him and love him but honestly, I don't believe a single word he says, everything is fabricated or exaggerated.
I think the problem is that he's always been addicted to dope, has smoked it heavily as long as I can remember and as a result has basically slept through his entire life. Its no exaggeration to say that he can sleep all night, then need a 2 hour nap at lunchtime and the same in the afternoon too. He has done so little with his life as a result, that he feels he has to make stuff up.
He's told ex girlfriends that he has been in the police and been in the army and has made up stories of mine sweeping in Kosavo. Just total lies.
He tries to tell everyone that he worked for himself for 8 years, or 12 years or 16 years (depending on how he's feeling that day) when we know for a fact it was around 18 months. It changes every time too, he's so off his face that he can't remember what he's told other people so can tell the same story twice with different endings!
He talks about an incident where he was arrested by the police at gunpoint and nearly 'had his head blown off' when in reality he was arrested and let go because his best friend had stolen some fax machines. We did have our house searched but as far as I'm aware it was a pretty standard police investigation for theft with no outcome as he wasn't personally involved. According to him though, our village was closed, there were loads of armed police and helicopters and the police came, took him away and brutalised him. No mention of this in the local paper or from anyone else at all. Apparently he had years of PTS afterwards which obviously gave him the perfect excuse just to sit at home, smoking dope.
I was watching the Usain Bolt film with him the other day and he started telling me about his amazing football career and how he needed physio after the games to keep him in tip top condition - he told lie after lie after lie, apparently they were injecting him in the shoulder with steroids at 16, he was made to do ice baths after each match, he had all these incredible injuries and was well known for being absolutely amazing etc etc... In reality he played socially for about a couple of years for a 4th division club, second team.
It's getting to the point that I don't believe anything he says. I wouldn't mind but it honestly doesn't matter to me what he has done or hasn't but I am personally offended that he needs to lie to his family and to our faces. He must think we're idiots.
