I've never quite understood why some people feel the need to clap when the plane lands. You do realize the pilot can't hear you, right? He's wearing headphones.
I can't remember the last time I carried a pocketknife.
Oh, there was a time when I did, but I was much younger then, and I don't have much use for one now.
So when the TSA announced it would allow air passengers to carry small knives on board, it didn't strike me as something that would affect me much...
