Causality?  


I send a message of love to you in a cloud of tachyons, 
Knowing that an onlooker properly moved 
Would say you sent the message to me
And that another onlooker moved differently
Would see a perfect mutuality of action.

NOTE:  A tachyon is a hypothetical faster-than-light particle.  

For reasons having to do with the Theory of Relativity one 
observer may see a tachyon moving from Point A to Point B while 
another observer sees the same particle moving from Point B to 
Point A and still another sees it occupying Point A, Point B, and 
all intermediate points at once so it has no specific direction 
of motion (infinite velocity).
