Afraid of my Pen

I'm afraid of my pen, It opens me up for everyone to see. My pen just flows with the thoughts that I think. Sometimes good sometimes bad, Then I write happy, then I write sad. The weather can change things, so can things I hear or see, Sometimes a flashing light, then perhaps a bent gnarly tree. I write about things I have done, I write about people I write about fun. But every word comes from me, They are all about someone and I don't like to offend, But I can't change the words once they have been penned.
