"Can you be my sister?"

Staring at her dark brown eyes, she remind me so much of myself when I was her age. Joyful, spoilt and painfully demanding at first but in the later years, quiet. 

How can I tell her that it is going to be okay when it may or may not? The future is grey.

What I can assure her is that I'll always be there as I wish that there will be someone there for me as well at that age.
