Thinking about it later, I realized that that's probably not the case, since the whole point of being a hostage is the guy gets what he wants or you die, and you never know when he might use you to let the cops know he's serious. But as long as he stayed calm... then, I don't know how calm a guy could be if he's holding up a bank. I watch way too much TV, though, so I can imagine some characters that would almost treat it as a routine. Of course, they're probably the types of characters who would calmly shoot you, too, so...
Although it is possible that we'd still be bored (unless we happened to have books or something), depending on the guy (or girl). We had about a million bomb threats in high school, and they stopped being scary at about the second one. One time, they evacuated the school during our calculus class, so while we waited for them to let us back in, we all decided to try to spell a word for the news copters. But it was the calculus class, so there weren't enough of us to spell out a whole word, so our teacher decided we'd do an H for Mr. H. Then we thought it would be neat to get the physics class to be an I for us and we could say HI to the helicopters, but the physics class was dumb and wouldn't cooperate.
Tonight I'm thankful for not being held hostage, my brain not melting, warm showers, butter soft enough to spread, and cheese popcorn.
I really hope all the hostages got out okay.
