Keeping your voice down and using headphones for music are also part of good etiquette. Giving up your seat to the elderly or pregnant women is a key sign of respect. This culture is not automatic; it needs to be learned and practiced by everyone.

This will be a significant change from some current habits. The organized flow of a metro station is very different from the crowded chaos of a bus stop. A polite and considerate attitude will make the experience better for everyone. When people follow these simple rules, the metro becomes more than just transport; it becomes a clean and comfortable environment for the community.

As young citizens, teenagers will play a huge role in this cultural shift. You will use the metro to go to school, visit friends, and explore your city. By adopting these positive behaviors, you can be leaders in creating a respectful public transport system that everyone can be proud of.
