Context: My step - mother was very fond of disciplining using an electric cattle prod . I grew up in the 70 's , so partying with drugs was normal , though my favorite was dropping blotter acid directly into the eyes . Yeah , kind of stupid as I look back on it and ca n't say I would recommend any of that now , hopefully , I ' m a bit wiser with age ! lol And unfortunately , may have contributed to my extremely high tolerance for narcotics ( though my father had this also ) .
