Every time I'm stuck behind someone who inexplicably stopped in the middle of a walkway to answer their phone, I just imagine to myself that it's a book and think of how engrossing the plot must be for them to pull it out and read it at the worst possible time, and at least I'm a little more amused than annoyed.

My favourite so far was teenage boy bicycling with both hands and both eyes on the phone on the way to school, crossing right in front of me in an intersection.
