“Girls will be your friends – they’ll act like it anyway. But just remember, some come, some go. The ones that stay with you through everything – they’re your true best friends. Don’t let go of them. Also remember, sisters make the best friends in the world.”
The latter part of this quotes is a truth I have only recently properly realised. When we aren’t arguing or going out of our ways to annoy each other, your sisters will fight your corner no matter what.
