there aren't many of them      
but                                                      
i think i can think of one at least              
it's winter here
summer there
yes, stating the obvious                  
but    
we'll never both be cold                                                                            
in your summer                              
you send me warmth to get me through winter                
in my summer                                
i'll send you warmth to get you through winter                

no, we'll never both be cold
