i decided walking in that it would be a better strategy to be honest about small things (like marijuana, and j-walking - which i'm brutal about), because if i told him i hadn't, and he thought i was lying, i'd be less likely to get approved than if i told him i had.
by being honest about the pot, and denying using other drugs, i established a level of trust that may have been decisive, in the end.
i mean, i don't think he would have believed me if i lied about the pot. he couldn't prove i was lying, but it might not matter. and then i'm in much bigger trouble...
