I always like to give some advice to my youngest sis being the eldest. I had walked the path I walked and made some mistakes along the way, I learned from my mistakes and I hope to share with my sis what I had learned. Sometimes I will give her advice such as "plan before you do anything" or something like "build up your merits now, cos if your current merits are depleted, you will suffer later".
They say the youngest is always the smartest because they have their elder siblings to learn from, I find it quite true for our case. My youngest sis is quite street smart.
By the way, I am turning 44 tomorrow, Hayley's Toby boy has the same birthday as me!
