IT'S NOT EVERYTHING IS BLUE.
                              
                              
                              
                              
                              
                              IT'S EVERYTHING IS RED.
                              (I'm dying inside please save me XD)
Roses are red
                              thorns are prickly 
                              from 1 to 10
