Castle of Cards

As a child, I remember building the castle of cards. For those who don't know what it is, a castle of cards is a structure created by piling up and balancing playing cards on one on top of another. I remember, everytime when I was just about to place the final card to complete my castle, the whole structure used to collapse. Its not like I couldn't ever make a complete castle of cards but just that even when I completed it, all it took was a single blow of air to ruin everything. This post is not about my experiences with building a card castle, but instead its about how fragile happiness is. Just like a Castle of Cards.
