Am I Invisible? I hope so!

My niece - who suggested I start a blog - now knows I blog. She's going to hunt for me. I just hope she doesn't know my grandmother's maiden name. I don't want her to know what I write about her uncle. I don't want her to know how I think of myself like a widow. She thinks we are loving and fun. I don't want to destroy that image for her - even though she approaches 40 - she's too young for the unvarnished truth [I'm thinking here of the plot to murder]. I hope I have obscured my tracks enough.
