Ironically, I've written more (very mild) swearing in my fanfic than I use in RL. There are times where Perry is 'telling' me that he would preface a remark with 'H*ll,' and so I write that to keep him in character. In RL, I would reserve that word for religious discussions.

In RL, I have averaged perhaps one swear word per decade of my life.

Joy,
Lynn
