What sucks is now that you fixed it, if anything in that office stops working within the next year, you're the one the blame is going to go to, and you'll have to go fix it. Wall clock near the printer stopped working? must be the IT guy who did something when he was here!
But yeah it's funny how people get genuinely scared of technology. I do recall being really new to computers and being a bit scared of causing something to mess it up, but that's mostly because I was a kid and if I messed it up I would have gotten in trouble. It was windows 98 at the time, if you did not mess it up, it did so to itself anyway. I learned pretty fast how to reinstall it and setup everything.
Lol see? But you learned something because you tried and now you have IT skills! That's how you develop new skills in anything. People don't realize that and get pissed when people suggest that they try.
