If you have to drive with the windows down in the winter, because you don't want the passenger (family members that called you for a ride) to smell the booze on your breath, and that would be the only way they could tell because alcohol barely touches you at that point, and you just act normal on doses that would knock most out. Also, you couldn't really turn them down for the ride because it is 10 AM and they know that you are home alone, so instead of explaining that you have drank half a bottle to get rid of the shakes, you just make the ride with the windows down, and smoke a few cigarettes so that you smell like smoke instead of booze. You then accept any gas money offered, and buy more booze with it.
