"I know you feel hesitant to rely on us. But we are here for anything you need. You don't have to put on a brave face or pretend everything is okay, becuase its not. If you just want to talk, laugh, cry, eat junk food till you're sick, or all of the above, just say it. Or if you'd rather we leave you alone so you can snuggle with with your fur baby's that's fine too." - Livvy to Sophie and Amy in Book 6: Nightfall
