Hidden in plain sight

I realized this week that sometimes my judgments keep me from seeing what's really in front of me. I'm sure we all do it but it was a really concrete example of it. Several years ago, I tried my hand at stand up comedy for a while and got to know a lot of local comedians. This week my brother invited me to go to a comedy show. While we were waiting for it to start, I casually observed the surroundings. I saw the comedy club owner and he was rushing around getting things ready to go and I saw this really old guy helping get things ready as well. I thought it was nice that there was something for an old guy who loves comedy to do. He was setting up recording equipment and doing various other tasks. I observed him multiple times doing different things to prepare for the show. The show started. We saw a few different people doing some opening work. They then called a comedian I used to know and I was really looking forward to seeing him after many years of not seeing him. Much to my surprise, up came this "really old guy" that had been helping set up the show. He probably is 20 years older than me but that's not as old as I had perceived this man to be and the thing that bothered me is that I hadn't recognized him. I had watched him several times and never observed his face well enough to know it was him. I just thought it was an old guy and went on about my business. It makes me wonder what I miss out on seeing in other ways. For fun, here is a picture of what he looked like when I knew him better and what he looked like the night of the show.
