There's no such thing as deleting an account from Facebook. I've tried several times but my account remains available to the public. I've never included any personal info in my account or posts, so I'm not concerned about it being used. But, it's very annoying that deletion really isn't an option!
Like you, I could write a book about my thoughts and experiences on Facebook! My grandkids want me to join Instagram so they can share things with me. I told them to send me a phone message, call me or, dare I say, write me a letter.
