it's actually very very difficult becasue you then get put into an uneasy hinterland between nursemaid and friend. so sometimes you will say, no i think you must stop drinking and doing cocaine this is a serious addiction you are struggling with and last week if you recall you were standing on a bridge at midnight on the phone to me talking about how you wanted to commit suicide....
you tell them that and then they go, shall we just have a few beers then, and next thing you know the cocaine is on the table too.
so its hard to negotiate
