- We should speak up about each other 's mistakes ...
- Be pleasant to each other -- just this once .
- We triumph over each other with human frailty .
- We immediately realized that we were kindred spirits .
- Outside of these they did not exist for one another .
- There is no love lost between the two .
- One could not encroach upon the other .
- The cables are parallel and equidistant from each other .
- When we were unhappy we could cheer each other up .
- The waves are out of phase and cancel one another .
