Didn't See It Coming

I was watching the news and heard a segment about a blind hooker who got stabbed 40 times.

At least she didn't see it coming.

Listen up, slowpoke: the phrase "didn't see it coming" usually means someone was caught by surprise, but here she was literally blind, so she couldn't see anything at all. You probably miss obvious things too, like common sense.
