Where the line is. . . who knows. I think autographs are fair, following the person around like a stray puppy is not.
Autographs are fair any time or any place? Is it ok for someone to accost her coming out of the bathroom? Or while she's studying? Is she that well compensated that she's entitled to no personal time at all? She has to be available 24/7 for autographs?
My take: Autographs and all of that are fine when she's "on duty," at an event related to her work. Any other time, she's "off duty" and shouldn't be approached for anything.
If it is a situation where it is fair to approach a normal person with a question (time, directions, etc.) that takes the same time, then it is fair.
I don't agree.
I have people approach me for the time and directions (happens in NYC often). It's not the same level of "intrusive" that asking me for something more personal is (an autograph is pretty personal, actually).
The time of day, how to find Rockefeller Center--those have nothing to do with me. There's a serious difference in the impact if you approach me on the street, in the coffee shop, and ask me something that's connected to ME.
