He was following his feet, left right left right, and then he saw the sea, and he watched the waves smash against the shore. He continued along the path, and it took him to a town, where a carousel of merry faces drew him in past misty windows, and he stayed awhile. He ran through forests, climbed mountains, and slept on buses. One time, the bus was a train, and then the train was a plane and it was going so far, so fast. He started getting uncomfortable and he couldn't see out of the window anymore. His suitcase seemed heavier but there was nothing in it.
He jumped off the plane and dragged the suitcase up the stairs. But with every step he took, three more appeared in front of him. He looked back, but the steps had vanished into the clouds below. He opened the suitcase. He was tired of carrying it. He got inside and snapped it shut.
At some point someone picked up the suitcase, with him in it, and carried it for a while. From the sound of their shoes pounding the pavement, he guessed they were lonely, and a bit peckish. But they also got tired of carrying it eventually, so they dumped it in the river.
He swam along like a salmon until he found his feet again. Left right left right, back to the start. Trying to run away from yourself will only lead you back to where you came from.
