The houses themselves are important signs. The straw house of the first pig is a sign of haste and not thinking long - term. The second pig's stick house is a bit more of an improvement but still not the best. The brick house of the third pig is a sign of wisdom and preparation. The wolf's actions like huffing and puffing are signs of his aggression and the pigs' need to be smart to survive.
The signs in the three little pigs story can be seen in many ways. The pigs' choices of building materials are significant signs. Straw represents a quick and easy but not very reliable option. Sticks are a middle - ground. Bricks show real effort and foresight. The wolf's attempts to break into the houses are signs of the external threats that we all might face. And the pigs' different reactions, like the first two pigs running to the third pig's house, are signs of the importance of unity in the face of danger.
Interpreting the signs in the three little pigs story is quite interesting. The three pigs could be seen as different types of people. The first pig might be the carefree type, building with straw. The second is a bit more cautious but not fully so with sticks. The third is the most responsible. The wolf is a sign of the hardships and difficulties in life. His inability to blow down the brick house is a sign that with proper preparation, we can overcome difficulties. Also, the fact that the pigs outwit the wolf in the end is a sign that intelligence and resourcefulness can triumph over brute force.
