Dear Matt and Mar,
I would like you to to go and search for lyrics for the song “What will be, will be”, I think it was originally sung by Doris Day (I think… lol).
I have no idea how the world would change by the time you two enter into adulthood, because whether it be technologies, the environment, social landscapes, political scenes, global economics and other important pillars of various societies, all seems to be changing at an exponential rate, some for the better and some not.
One can only assume that all parents want the best for their children, at the moment you are 4 and 7, and sleeping soundly next door, lol. Right now Matt wants to be and Engineer/bus conductor while Mar just want to sing and dance and be a Princess in pink, haa haa haa.
Soon enough responsibilities will come, social and peers pressures will come, pain and heartache will come, also happiness, fun and laughter will come too.
All we can do is sit back and try to be there, to be there with the appropriate support, to be there with the right advice, at the right time and hope you two will grow up to be someone that is happy with yourself, the world will keep spinning, things will change and so will you.
