Happy Birthday, Big Sister!

I just remembered that yesterday was my sister's birthday in Singapore but it's my sister's birthday TODAY in America! How could I have forgotten? But I still can't believe my mom forgotten... She was like 'Oh really?' when I reminded her that it was her elder daughter's birthday. So weird, right? Anyway, HAPPY BIRTHDAY, BIG SISTER!!! You should be 23 years old now... Why are you ten years older than me???
