So lets say someone is reading the paper on the subway next to you. You see an article of interest and begin reading over their shoulder unabashedly. Do they:
a) Skillfully use the paper to give you a nasty papercut?
b) Hand you the paper when they're done?
c) Angle the paper such that you can't read it?
d) Angle the paper such that you can read it?
e) Switch to a section they know you won't be interested in - like sports?
