Hi! I'm sorry to hear about your parents. How old were you when they died?
I was only 5 when I became an orphan. They both died in a car accident. 
That's really sad. How old was your brother?
He was 8. Its really rare to lose both your parents at one time and become an orphan. 
Who took care of you guys after you became orphans?
We went to a family who had a half orphaned son, he had only lost his dad and his mom was still alive. 
I guess I'm half orphaned, too. I never really thought of it that way, but my dad died in a motorcycle accident. Did you know this family?
I don't that phrase is very popular but i have heard it before. They were family friends. Its normally used when a child has only lost one parent. Sorry about your loss
