[Reef]

I have a little sister. My aunty has an older boy and younger girl. My mom and aunt are sisters.

just hold on, I'm getting to it.

I'm born on the same day, 6 years after, as the male (my cousin). And my little sister was born on the same day, 17 years after, as the female (her/my cousin). I'm not quite sure if I've worded that right
