This is the insect world version of the ugly duckling. The cute ladybird beetle started life as a fierce centipede look-alike creature.
In the human world, the closest equivalent i ever observed is my nephew. He used to be a naughty and spoilt brat in his younger days but after going through army and NUS, is now a soft spoken gentleman.
So, we are not what we used to be. We change. From bad to good. Or good to bad. We will never know what we will become. Be mindful and aware and hopefully we will not be too far away from the middle path.
