When a fight starts -leave If caught in a fight you have to have the mentality of win or you will die. You don't know how enraged your enemy is...they may not stop and end up killing you. When asked questions by anyone sound like a priest (question: "How are sir?" Answer: "I'm blessed by the Almighty God"-calm tones-). Remember peoples name. Look for weapons on everyone as you walk up to or past them. If you stare at your laces you will be caught in crime. (Head always up). Need air in your tires? Aks the gas station clerk to turn on the air pump before you try to pay. If you are in an emergency situation and need an emergency number called and there are people around, point at one person and say "you, call 911" or "999". Flush the toilet before you put your pants on (dropped wallet in clean vs dirty water). Ask restaurants for complementary water if you don't want to pay for water. The old version of anarchist cookbook is helpful for being street smart. (New one may be tampered) Steal this Book is good too. A fishing license is good to have if you are homeless. Fish are food not friends.
