Oh God, this brought back a traumatic memory. I was hanging out after hours at our office to look after a meetup group that was using our space that night. Nothing tricky, make sure people can get in, keep the lights on, make sure nobody sets the place on fire.
I was plugging away on my personal laptop which had Linux on it. Having a great time doing something or other when one of the meetup organisers approached me with a USB stick and asked if I could help them print out some signs to help people know where to go.
My install was rock solid, fast and set up exactly the way I wanted, but in that moment none of that mattered because it was me who froze. I thought back to all the decisions that lead me to that situation, even the conversation with a coworker a few months ago about Linux who literally said "I love Linux but one day I'm just afraid I'll have to print something or whatever and I won't be able to". How foolish I was to dismiss the wisdom in his words that day, and now my worst nightmare had come to pass.
I swallowed hard, looked the organiser in the eyes, and told them I couldn't help them. I didn't even try. Best to rip the band-aid off, disappoint them now and get it over with. After the glaring admission left my mouth I waited for the inevitable response. I was a fraud, nothing more than a self proclaimed computer geek who couldn't accomplish a rudimentary task despite all my time studying and tinkering. It was over, I guess it wasn't imposter syndrome after all, I really was an imposter and now I'd been discovered.
But instead the the organiser just smiled and said "that's totally ok, we were just a bit disorganised and didn't print it before coming this time. Thanks for your help anyway!" And everything was fine. This time.
