Imagine you have a bunch of people in your family, like your uncles, aunties, grandparents, and cousins. Cousins are people who you're related to because your parents have brothers or sisters who also have kids. So, you and your cousins are like second brothers or sisters.
Now, sometimes there might be some problems with your cousins, like not getting along or arguing about things. It's normal to have small disagreements with people, but if the problems continue, it's good to talk to an adult like your parents or a teacher. They can help you figure out how to solve the problem with your cousin in a nice way.
Remember, family is important and we should always try to be nice to each other!
