Imagine you are playing with your toy cars and one of them gets stuck under the couch. You try to reach it, but it's too far for you to grab it. You might start crying because you really want your toy car back.
In real life, when people get sick or hurt, sometimes they need extra help just like you need help getting your toy car. When someone gets really sick or has a big accident, there is a special kind of car called an ambulance that helps them. The ambulance is like a superhero that comes to the rescue!
When someone calls 102, it's like they are calling for the superhero ambulance. The person on the phone asks what's wrong, just like when you cry for help because your toy car is stuck. If it's an emergency, the ambulance will rush with its loud siren and flashing lights to the place where the person needs help.
Inside the ambulance, there are people called paramedics who are like the ambulance superheroes. They are trained to help sick or hurt people. They have a lot of tools and equipment in the ambulance to help the person feel better. They can give medicine or bandage up a wound, just like a doctor would. They also have a stretcher to carry someone who can't walk.
When the ambulance gets to the person, the paramedics quickly get out and start helping. They ask the person questions to understand what happened, just like how you ask your friends what happened if they fall down at the playground. They make sure the person is not in any danger and take them to the hospital if they need more help from doctors.
Sometimes, when the ambulance is taking someone to the hospital, they have to drive really fast. But don't worry, they are trained to drive safely even when they are in a hurry. They have special lights and sirens to let other cars know they need to go fast, and everyone tries to move out of the way to let them pass.
So remember, when someone is very sick or hurt and needs help, they can call 102 for the ambulance superhero. The ambulance will come quickly to the rescue, and the paramedics inside will take care of them and make sure they feel better.
