"Promets-moi simplement que tu penseras à moi chaque fois que tu regarderas le ciel et verras une étoile."

Simplified Meaning:

When someone asks you to remember them whenever you see a star in the sky, they are asking to be in your thoughts even when they are not around. Stars are a constant part of the night sky, and looking at them can serve as a reminder of that person. For example, if you move to a new city and leave behind a close friend, they might ask you to think of them whenever you see a star. This way, you feel connected to them despite the distance. In day-to-day life, if you miss a loved one, seeing a star can bring back warm memories and make you feel closer to them. It's like having a special, secret way to stay linked, no matter where you are. To apply this idea, choose something that is often present in your surroundings, like stars, which can act as a trigger to remember someone you care about deeply. This can bring comfort and keep the bond strong, even if life takes you far apart.
