Tell us if this sounds familiar: A commuter is reading something salacious on the subway — say, “Fifty Shades of Grey” — when a fellow passenger happens to glance over and see the material. The shared moment is one of mutual embarrassment.

Yet this could lead to awkward moments like it did for this Post staffer: She was reading on her Kindle and came upon “a particularly embarrassing passage” while aboard a Red Line train. She noticed that the man next to her was reading over her shoulder; they both turned red, and he switched seats at the next stop.

We want to know if you’ve experienced something similar. What’s the most embarrassing thing you’ve read on the Metro or the bus? What’s the most embarrassing thing you’ve seen someone else reading? If you are reading “Fifty Shades of Grey,” do you cover it up or read it proudly?
