Emil sticks his tongue out at me and tries to soak me. At the last moment, I manage to deflect the spray of water with my coat. We put the cleaning equipment back and walk on.
As we go, we still have a number of challenges to tackle. We keep a look-out for animals. We practise long jump. And we learn what makes an echo. The path to the last two stops leads through a long tunnel.
“Is that Charly’s tunnel?” Emil asks. I ask myself who this Charly is. Then I remember. Grandma sometimes talks about Charly. Charly was a train. A very slow train. Charly ran between Echternach and Luxembourg City. On the way, it stopped in Bech. Charly hasn’t run for a long time. But the tunnel and the station are still there.
At the end of the tunnel, Emil suddenly turns round.
“Do you think Charly also has an echo?” he asks me. I shrug my shoulders. Emil makes a funnel with his hands and calls out loudly: “Choo-choo-choo-choo.” From the other end of the tunnel, it echoes back: “Choo-choo-choo-choo.”
“Be careful that Charly doesn’t run you over,” I say. Emil jumps to the side. I burst out laughing. Emil has to laugh too: “You scared me then!”
