you never know

Like you never know where it's going to go.

I mean, you never know, but it's very unlikely in itself.

Trump has been sneaking out millions of barrels of oil from the Strait, and you never knew about it, because it was never reported.

You'd never know about all the horsepower underneath your foot.

Even though you’d never know they’re there, some combination of drains and cutoffs were probably installed to keep the structure safe and sound.
