I honestly think hr was so regimented for so long..... that when he retired, he cut loose and lost control a little bit... basically what happemed to me with ky drug addiction. .. I grew up in a very regimented household, very strict, very disciplined. .. didnt even drink until I was 20.... and I went put and partied with some friends a couple times and tried blow once, and thats all she wrote.... the feeling of getting high and leaving my responsibilities behind was very powerful (especially since I had a part time job since I was 12, and I basically always had adult responsibilities and a very regimented family life), and I totally lost control... next thing I knew I was shooting meth and heroin.
Once I realized I didnt HAVE to be as disciplined and regimented as my parents had pushed on me my whole life,I went fucking nuts.
I see something similar in Dorian.
