A two way street: Communication pt. 2

When you travel there is always two lanes on the road one lane going in both directions. So when it comes to communication it works both ways. There should be information going in and out like two lines of traffic moving on a normal evening. It shouldn't be no traffic jam because that would means less communication is going on. However if you know how to drive then traffic jams wouldn't happen. So the whole meaning behind this metaphor is communication is like a two way street.
