Real Relationships are not Perfect and Perfect Relationships are not Real

Couples who fights more often are most likely stronger than those couples who do not. 
What greater thing is there for two human souls, than to feel that they are joined for life--to strengthen each other in all labor, to rest on each other in all sorrow, to minister to each other in all pain, to be one with each other in silent unspeakable memories at the moment of the last parting? - George Eliot, Adam Bede
