There is a lot to read into this if it were true, but we need to remember that TMZ is posting a story told to them by someone else. Did they check this story out to make sure it's fact? I don't think so.
At any rate, this is Oprah who goes to war torn countries and hugs starving, sick, people. This is Oprah who goes into the audience and jumps up and down in excitement with them while holding their hands. So, I really don't buy the personal space issue as I believe Oprah herself would have intervened if there was a problem. And...she was in Mr Jackson's home, not the other way around. Just saying...
The ending [Personal space -- it's not a joke.] says a lot and hopefully TMZ and the rest of the media will take note and practice what they write. TMZ - if you read this, quit pointing fingers at others faults until you can practice the same respect.
Sorry, not my cheeriest of days. Blessings to you all.
