Imagine you have two toys that you really like to play with. You also have a friend who visits you often and wants to play with your toys. Now, you have to make a decision on which toy to give to your friend so that both you and your friend are happy.
The idea of equal consideration of interests means that you need to think carefully about what your friend likes and what you like, and then try to choose a toy that you both enjoy playing with. You need to treat your friend equally to yourself and think about what is the best for both of you.
This works the same way in the real world, where people have different interests and needs. It's important to listen to each other and try to understand what we all want, so that we can make decisions that benefit everyone equally. It's a way of being fair and respectful to others.
