One of the hundreds of reasons why I love Sydney is the probability of catching a glimpse of Rainbow. Before arriving here, I can remember only a handful of occasion when I had seen this gorgeous natural phenomena. But here if the rain and sun decides to show up together, there's a high chance that a Rainbow will adorn the sky. This is a sight that always makes me happy.
I also love how on half the sky is cloudy grey while the rest is clearer and blue.
