All walls are twofold and have two faces. What is inside and what is outside depends on which side of the wall you are looking from.
Walls can serve as both a boundary and a protection. They can keep things in or keep things out. Sometimes, they create a sense of security and privacy, while at other times, they can seem like a barrier that prevents us from seeing or experiencing something.
Moreover, the perception of a wall can vary from person to person. One person may see a wall as an insurmountable obstacle, while another may view it as a challenge to be overcome. It all depends on our perspective and our attitude towards it.
In conclusion, walls are a complex and multi-faceted concept. They can have both positive and negative connotations, and their meaning and significance can change depending on the context and the individual.
