How Do You Make Friends? - Friday

This is Miss Manners in reverse.

Do you ask people what they are reading? When they are sitting near you in a doctor's waiting area, or the subway or wherever? Or do you steal glances at the cover and try to read the part of the title that isn't covered by their hands?

And have you ever had someone ask you? Do you rattle off the title without taking your eyes from the page? Or do you offer a full synopsis of what you've read thus far?

What do you think? What do you do? 
Thanks for stopping by the blog and helping me satisfy my social-reading-etiquette curiosity!
