I read this in my primary school reading book in the '80s, I believe the author name was English but I'm not sure. The story goes something like this:
An employee of some sort of galactic federation shows up to its boss to mention that people on Earth have finally harnessed atomic energy.
The boss, a tall alien, is happy and proceeds to write down "Terra, coordinates X, Y, Z" in a big list of space faring civilizations, then asks when should they expect these new people to show up.
The employee, embarrassed, admits that while earthlings have mastered atomic bombs, they have not mastered space travel.
The boss is appalled by the fact that someone may consider using atomic bombs on their own planet, and proceeds to strike out the line he had just added, for the first time in history.
