Brothers and sisters are siblings. They are people who have the same parents.
Having siblings can be fun because you can play and talk with them.
Examples:
I have two siblings, a brother and a sister.
My siblings and I like to play together.
She is my sister, and he is my brother. They are my siblings.
My siblings always want to eat my snacks!
I have a million siblings, and we all live in a giant house together.
My siblings and I are like a team, always helping each other.
