Alcoholism
I become more and more convinced of the personality damages produced by a long and constant use of alcohol.
Some alcohol-abusing people that I observe have increasing difficulty in finding words to construct informative sentences.
They also have troubles with long-term memory and that means trouble and boredom for me too, because I have to keep repeating everything I say...
Their minds become so focused on their addiction that all their jokes are about beer. Drinking is all their fun and they cannot understand how other people can have other forms of fun...
They think that, by drinking, they are enjoying life, but they don't even have an unaffected consciousness anymore to trully and fully experience their existence. In fact, they don't even have a personality of their own anymore. The little that rests is a contradictory mix of false behaviours. There's no essence, there's only appearance. No happiness, only false smiles. No feelings, only words and no comprehension of the emotions of the silence. No real interest, only the need to appear interested, in order to become interesting.
They become weaker and weaker in resisting this enigmatic life. They try to fulfill the lack of purpose of life with unnecessary objectives and they think that other people can solve the enigma for them or make them stronger, or make them believe they are not losing their essence... So they believe in every pseudotheory and they still drink...
