Sometimes it's incredibly easy to pick up things from public figures, because we're exposed to them alot. But it's good to remember that what we pick up is definitely not the whole story. They are people like everybody else though, and it can be very hard on people to be in the public eye. I get a 'vulnerable' sense of many celebrities, but part of it is definitely that they put themselves out there and/or is put in situations they cannot really control.
Now, I have a much deeper connection with fictional characters than with actual people alot of the time - but that is another story.
