doesn't anyone realize that i'm making it all up as i go?

So this is funny: I've been dubbed the "resident expert" on computer issues in my office. I find this hilarious. I spent about an hour this morning helping a judge figure out how to use PowerPoint. I have used PowerPoint about twice EVER. I was very open about this fact. Yet, I was somehow very helpful. He was trying to insert a picture, and I told him, "Well, you probably go to 'insert' and then choose 'picture.'" Then, my coworker couldn't print out some labels. By some fluke, I figured out that some of the text was hidden. They think I'm so smart, but I CAN'T EVEN GET MY INTERNET TO WORK PROPERLY!!
