I think it's better to have brothers and sisters. They would protect you and help. You should also take care of them. You could always ask them to play with you, to help out in difficult times. If you have no one to take a walk, call them yourself. In general I think to have a brother and sister, it's cool! Если у тебя есть братья или сестры вот пример:
1.I have a sister, Julia. She is very kind, beautiful, responsive and intelligent. She is older than me by one year. We are always a lot of fun together! It is not only for me but my sister and best friend. She worries about me, try to help, does not reveal my secret and is always there when needed.2.I have a brother, Andrew, he is younger than me by 2 years. He is very cute and clever.He always tries to help me, even when you do not know how. He always plays with me. Even if we fight, we still love each other and quickly put up. We do not reveal secrets and woes, they will remain only in our heads. We are connected with it, I can not live a day without him.
