How it works
怪不得 marks the moment a puzzle is solved: having just learned the reason, the speaker says the result is no longer surprising. It pairs naturally with 原来.
Examples
原来你没睡好，怪不得没精神。
Yuánlái nǐ méi shuì hǎo, guàibude méi jīngshen.
So you didn't sleep well — no wonder you're listless.
怪不得这么冷，下雪了。
Guàibude zhème lěng, xià xuě le.
No wonder it's so cold — it's snowing.
