Born leap year

The girl- 8 years old/narrator name; probably grace; My parents told everyone I died at birth, I’ve been living in our soundproof basement for 16 years! They say I’m cursed because I’m a leap year baby And can only exist on February 29th Mason, 7 years old: THERES A GIRL DOWN HERE! The mom; it’s just a ghost! Luke; What? No it’s not… Mason; what are you thinking mom, your schizophrenia is getting the better of you.
