"Happy Birthday Teenage boy, you have entered teenage.....I will be honest my dearest,  that it's a very hard phase of your life. You grow, yet your not entirely a grown up person....Go to Dad,  and tell him to check Mama's wardrobe,  If he has retained my things then you will get a gift box over there. Mama got it for you, I didn't knew you would be a boy or girl, so in that box with yellow gift wrap, there is also a beautiful bangle, maybe give it to your wife. Oops.. Mama can talk about wife right? Haha... After all my boy is all grown up. So why am I giving it to you now? Because Son,  this is a difficult phase, but I want you to continue to be as excellent as you are, many kids leave their childhood goodness in this phase,  I don't want you to.. So this is like a kind of corruption... Haha... Mama loves you a lot... I don't know if you have done this but go back and read all the letters Mama has given to you, this will be a good exercise, for you to understand... What you meant to Mama and also how you should be good always.... Though I agree that some people maybe bad. Now my boy,  you're grown up so mama will talk about it,  okay? So in this world like there are good people there are bad ones to,  but my darling son, you should not assume that because of some bad people all are bad, because they aren't... Son, but how will you deal with these bad people? Well, Tit for Tat, as Mama has said before,  Mama was never very emotional,  until it came to you. So I don't expect you to be very good, no matter what, no,  just be good to poor and weak and those good to you. With others,  well don't be a demon,  but what they do, so shall they reap... Don't waste time on revenge, but don't feel helpless either, punish if you can.... This time Mama is talking more practical right? But go back and read all the letters,  so it will help you retain the goodness..... Be optimistic, I hope you know what it means..
and also still slightly good... You will take on family business,  so Mama had to say all this, sometimes you should know how to handle all of this... Mama is thinking to much and as usual burdening my baby boy's little shoulder..... No? My grown up son.... I love you so much..... More than the number of particles in the sand near ocean.. Love you. Take care of yourself...."

Yours preparing you for the world yet expecting you to be good,
Mama(with all her love but also with what all her little soon to be dead brains could come up with)
Don't cry... Go and be happy... God will always protect you.. My darling son..
