Once I brought balloons to school and asked the children to take them and write their names on them.
Then all the balloons were taken out into the corridor and I mixed them. Then I gave the children 5 minutes for everyone to find a balloon with their name on it. The children ran to look, but time ran out and no one found their ball...
Then I asked the children: take the balloon that lies nearby and give it to the person whose name is written on it. It took less than two minutes and everyone had their own balloon in their hands.
And then I said to my students:
Balloons as happiness. One will not find it if he searches only for himself. But if everyone cares about each other, you can find it faster.

Thanks to everyone who brings warmth and care.
