why to we write about love

I think we use the written word as a way to express our emotions.
People do not always know how to express their emotions, or do not have anyway to act upon their feelings, so they do the next best thing, they write, and get it out there,  for the world to know.

Shakespeare

I'm not sure what the big deal with Shakespeare is, but from what I've heard he was a big contributor to the English language. He wrote many plays, and had a big impact on literature.
Once you understand how he wrote and are able to decipher the English "jibberish" you realize that he had a great sense of humor burried withing his tragedies. I personally really enjoy shakespeare.
