Once upon a time, there was a big tree that lived by a river. The tree loved to watch the water flow downstream and always wondered what was upstream.

One day, a user came along and asked the tree if it had ever explored upstream. The tree replied that it had not but would love to see what was up there.

The user suggested they both go upstream together. The tree agreed and they set off on their journey. As they went upstream, they saw all sorts of amazing things they had never seen before.

After a while, they reached the source of the river and found a spring. The tree was so happy to finally see where the river started. The user then explained that just like rivers have a source, software also has a source code which is constantly updated to create new versions.

The tree was amazed and realized that just like the river, it too could continue to grow and change with each new version. From that day on, the tree was grateful for the adventure and always remembered the lesson it learned from the upstream journey.

Reflections

1. What was the tree's initial impression of upstream?
2. Why did the user suggest exploring upstream with the tree?
3. What did the tree learn from its journey upstream?
4. How is the source of a river similar to the source code of software?
5. Why was the tree grateful for its adventure?
