computers and Dolly Parton

I think there should be an easy way to get answers, like how do you UNfriend someone on Google after you've made a mistake and made a friend of them? Plenty on how to do, not so much on how to undo. Like what if I wanted to delete this blog? Abandoned blogs litter the landscape of the internet and maybe we need to know how to delete them. Just sayin....
Anyway I saw Dolly Parton on a morning show who cheerfully admitted to being 65 years old and wow if she doesn't look like she always has to me, who has followed her career from the times when singles were those little 45's and I had stacks of them all the way to the ceiling. (Which my mom threw away along with all my Barbie Dolls, some of these records are worth money now) She still has many secrets, but not one is her burning ambition. She always wanted her career so much. My sister-in-law still has her album with "Two Doors Down" on it on which she is dancing in blue jeans with a red and white checkered shirt, so Beverly Hillbillies, and loves it more than any other. She also loves the movie "Tammy". I think Dolly's voice, which is like no other should have been what kept her famous, but instead she is an actress which I think she is not very good at. One thing anyway, she is an original whatever she is!
