I wish I can GLuE people together.
See, if you're stuck together, we can talk, face to face. we can even play games. If you don;t face each other, nothing will start.
Everyone has a present and has a past. In order to understand, people need to talk face to face and let their feelings crash into each other. Even families can't understand things unless it's put in words. It's even important when you're not blood related. But facing another person means that you might both hurt each other, or end up hating each other.
However, pretending you understand someone else not saying anything is even worse.
and that's what makes "trust"
Think about it.
