A little note for fun...

- Ah, I see that there are well-advised people in your residence!
- Thank you; but how did you notice it?
- You installed a speed bump in the entrance of the courtyard to force cars to slow down.
- Yes...
- You did tremendously well! People are crazy; they drive at insane speed, without taking care of pedestrians!
- Consider however that before the courtyard and the speed bump, there is a barrier you have to open.
- Yes, I saw it. But I know them very well! They rush forward as soon as the barrier gets open, barge into the courtyard if nothing prevents them from it! Good thing you put the speed bump!
- You know, the barrier is just three meters from the speed bump.
- Never mind, you did well! You are never too careful!
