Okay kiddo, let me tell you about something called "Gandhigiri". It's a way of solving problems without hurting anyone or causing any trouble.
You know when sometimes you have a problem with your friend, and you get really mad? Well, instead of shouting and being angry, Gandhigiri tells you to stay calm and try talking nicely to your friend to solve the problem.
This idea comes from a very special person called Mahatma Gandhi. He was a very important person in India who fought for freedom in a peaceful way. He believed that kindness and non-violence were the best ways to solve problems.
So Gandhigiri means doing things the way Gandhi did - with kindness and non-violence. It's like being a superhero who can solve problems without ever hurting anyone!
