Expressing “Coincidentally” with “qiǎo”

真巧，我正想给你打电话，你就先发消息过来了。

Zhēn qiǎo, wǒ zhèng xiǎng gěi nǐ dǎ diànhuà, nǐ jiù xiān fā xiāoxi guòlái le.

What a coincidence. I was just about to call you when you messaged first.

那天我本来只是顺路经过，没想到碰巧就遇见了多年不见的老同学。

Nà tiān wǒ běnlái zhǐshì shùnlù jīngguò, méi xiǎngdào pèngqiǎo jiù yùjiàn le duō nián bú jiàn de lǎo tóngxué.

That day I was merely passing by on the way, and unexpectedly I happened to run into an old classmate I had not seen for many years.

事情偏偏这么巧，我们刚准备出发，外面就开始下大雨了。

Shìqing piānpiān zhème qiǎo, wǒmen gāng zhǔnbèi chūfā, wàimiàn jiù kāishǐ xià dàyǔ le.

Things turned out to be such a coincidence: just as we were about to set off, it started raining heavily outside.
