You are going to meet your online friend offline. He is a friend you have known for a long time. To be honest, you don’t know much about him, but from your conversations with him, you can feel that he is a good person.

The taxi driver follows the address you gave him and turns into an underground tunnel. After driving for a while, you receive a text message on your phone: "Welcome to the Giant Residential Area. Please drive on the human-only route and pay attention to ground vibrations and overhead..."You suddenly remembered that you had never asked your online friend if he was a giant or a normal-sized human. You were just chatting about things that interested you and didn't care about each other's identities at all. Your phone vibrates. It's a message from him: "Are you almost there?" You type back: "Yeah."

Taxis drove along the pedestrian lanes reserved for humans, and the footsteps of giants shook the ground. Giants looked no different from us, except they were hundreds of feet tall.
