Patient discussion about quarter

Q. What would you do if a friend showed up to your house and pulled out a quarter pound of cocaine? True story: What would you do if a friend showed up to your house and pulled out a quarter pound of cocaine, and a bunch of other narcotics all bagged up individually, and then asked if you wanted the first go at them?

A. First of all, I'd probably go ‘Hey, what do you think you are DOING with all that! And why the hell are you at my house with this load of rubbish?? But then I'd probably calm down a bit, and we'd go round to the police station, just round the corner from my place and hand it in. I have a lot more conscience now than I used to and there is no way I am going to encourage a situation like this!
