Sure, I can help you with that. Here's a detailed description of the route from the school to the supermarket in English:
First, I exit the school building and turn left. I continue walking straight along the alley for approximately 5 minutes. After walking for 5 minutes, I reach a road. I use the pedestrian crossing to safely cross to the other side of the road. Once I am on the other side, I keep walking straight, passing by a restaurant on my way. After passing the restaurant, I continue walking until I reach the supermarket located next to the Billa store.
