Do you have a sister or brother??? If so you will know that sometimes you fall out and get angry at each other, but at the end of the day you are related and you will always be.
My sister is younger than me which means that I have to look after her, sometimes i don't want to but it is my role as a big sister.
This is me and my 9 year old sister, Arwyn (who looks like 13 as she is nearly taller than me!!)
She may be a weirdo, BUT SHE IS MY WEIRDO!!!! <3
