When it rains, it pours

खल्वाटो दिवसेश्वरस्य किरणैस्सन्तापितो मस्तके
वाञ्छन्देशमनातपं विधिवशात्तालस्य मूलं गतः ।
तत्राप्यस्य महाफलेन पतता भग्नं सशब्दं शिरः
प्रायो गच्छति यत्र भाग्यरहितस्तत्रैव यान्त्यापदः ॥

- नीतिशतकम्

A bald man scorched by the rays on sun on his head, seeking shade, guided by his fate, took shelter under a palm tree hoping to get some relief. But then, a big fruit fell from the tree, with a loud noise broke his head and killed him. Usually, troubles always follow an unlucky person wherever he goes.

When it rains, it pours.
Anything that can go wrong will go wrong.
