Getting valuable infromation by listening to someones else conversation

Listening to someone else conversation on bus, while trying to read newspaper in bar or just when walking down the park can be both fun and informative.  

Valuable information is floating in the air everywhere.

Example: Parent returns from trip and then calls a relative and tells a story from trip. At the same time parent has told a story his son was listening to that story (When talking on cellphone there is potencial to for more than one listener, conference).

Stationary phones can be postitioned in passage, so it offer some privacy while keeping possibility to be heard all over the place.


So next time nobody wants to listen: Walls have ears too. Keep 'em informed!
