New Job Oops

So yeah, first day at my new job and I managed to hit the print button way too many times. Like, 50 copies of the same document. And they were all about this big project that's supposed to be super confidential. My boss saw me printing them and just gave me a weird look before he went back to work. But you know what? It was already late in the day so no one else was around. I hope nobody else finds out, but honestly, I'm kinda freaked out by how easy it is for something like this to happen.
