I am no longer interested in meeting him, but at one time I was. Why do you find that strange?
It's not strange but I don't understand it.
What makes a person wait for maybe even hours just to get a quick glimpse of someone?
It's basic human instinct that dates back to the days of the cavemen when the herd's of cave dwellers would look for a leader, someone to admire, someone to look up to, someone to rely on.
Today it's a little different, but most people need someone to admire, and part of that admiration is the desire to have a face to face encounter with that person. Because it's usually so rare to achieve that, it makes it even more desireable. There is a certain rush most people get from having someone they (and millions of others) admire address them, that they will go to great lenghts for it.
Of course not everyone is that crazy. But many people are.
You might not go out of your way to meet Tom Delonge, but I guarentee if you saw him on a street corner, you'd get that same rush. I know you'd certainly walk up to him.
My dad hates celebrities with a passion and doesn't get the obsession, but when he happened to meet Steve Martin in NYC a few years ago, even he admitted the experience was pretty cool.
