The Golden Rule

Three:
-I like how me and Kyle like the same type of music.
          
-When  read his blog i was happy/surprised to see that he knows his history of the trumpet.
         
-From what I've read Kyle's a sporty person .

Two:
-I think he should put up stuff like what he likes to read, his books and t.v shows and why their his favourites.
        
-Aside from fun and games i think he should put up a post about something hes really interested in.

One:
-Can you explain the golden rule a little more?
