There is a famous game of hide and seek, it always feels good to play this game, doesn't matter what age you belong. The best part of the game is that you are curious always, about when you have to hide or when you have to find someone who is hidden somewhere.
How about looking inside you or finding out something which is hidden from you. There are many things that perhaps we haven't explored about ourselves and they remain hidden unless we accidentally or due to some circumstances come across that hidden quality of ours.
We deal with so many things in our lives that we don't really know about many things which we do have but we never acknowledge that. The hidden side can be dark or bright but we do have a hidden side.
It's better to come across the dark side of ours so that we can improve upon and be better to overcome such a thing, while the brighter side will always bring joy to our face.
