wonder if he is using something in addiction to alcohol.
bizarre if you ask me.
my addict posted a "note" on facebook. i don't know if he was using at the time, or just had been, but it was strange and sad, cryptic, and calling out for help. wanting to get out, but locked in the prison of addiction.
that he would be so wrapped up in his own strangeness and other world, oblivious to you son, means (to me) that it doesn't matter what was going on. he is ill and i hope your son doesn't have to face this again.
it makes me sad.
