All the promises we're made,
From the cradle to the grave,
nature, will break.

What's that law, that says that the worst thing will most likely happen at the worst time possible?

Murphy's Law, that's it.

It's the small daily things that we've come to take as normal. However, when we scrutinize these things, we realise that there is a pattern. All of these have happened to me on various occasions:

When at the bus stop, every bus except the one you need to take arrives.

Your side of the road never has free taxis driving on it.(classic!)

When you need something from the heap of stuff at the 'sale' cart at Isetan, it's always at the bottom of the heap.

The same day you forget your umbrella is the day it rains.
