The Baltic Entente is like a friendship club for three countries called Estonia, Latvia, and Lithuania, who all live next to each other in Europe. They made an agreement to work together and support each other, just like how friends help each other out.
They talk to each other a lot and share their ideas and problems. If one of them has a big problem, the other two will try to help them solve it.
They also do things together, like playing games, going on trips, and even doing homework together. By doing things together, they learn from each other and they can make their friendship stronger.
The Baltic Entente is a great way for these countries to work together and help each other out, just like friends do.
