Write What You Know

How many times do we hear this? And yet, we try to transfer our experiences, our knowledge, into fiction. Well, a bunch of writers I know do this, and so do I.

The question is, how do you deal with friends or loved ones who think you're writing about them? Many times I try to imagine crazy things, but that doesn't mean it's based off anyone near and dear to me.

Just curious what the writers out there think.
