The volcano subsided.

After about 24 hours of "Cold War", me and my mum are in talking terms again. But somehow, my mum left me a question. 'Why am i always jealous about me sis?' Well this question have been puzzling me for sometime. I still don't have the actual answer, but i know i will get it sometime later. Maybe it's because of my relatives that always like to compare me to my sis starting from the day i was born?
