Story of Chinese Leaf

When my sister and I was about 11 or 12, we were sent to the supermarket to get some Chinese leaf.

My sister just pick up the first one from the box.  I look through the box and got a nicer one.  When we got home, my vegetable was a bit rotten inside, while my sister's looked sad outside was okay inside.  My mom then said I was vain to choose the nicer looking one.

My sister is this happy go lucky, let life takes you kind of person.
I spent my time in search of better life, and sometimes worse off then my sister.
And my mom is simply insensitive and shallow.
