I'm writing a book and I am struggling to write the relationship between two sisters. They are very close and 8 years apart in age.
The older one is called Reagan (she is 16 years old) and she's quite protective of her family but she's quite snarky and torments her sister. She values family over anything and everything.
On the other hand, Melian the younger sibling who is is 8 is quite reckless and nonchalant but can be quite grumpy or aggressive. They are not the type of siblings who snitch on each other though.
