One other thing. If you are in the entertainment industry, people know you.
When you show up in their town, its a special event for them. They want to party with you on their big night out.
Never mind youve been doing this every night for a month, this is THEIR big night, they want to buy you shots, get high, go do a few lines.
The next day, they are nursing their hangover, and you are back to the next people on their big night. Its not too long before that IS your life.
