Good morning, Chris;
Do not feel bad or embarrassed. That is a very simple thng, and it should not get in the way of your enjoyment of the camera and taking photographs with it -- the last point is the goal, after all.
I do not just do photography. As the radio guy for a local ski patrol, last night I was told about a radio that did not work properly when it was picked up by a patroller just that morning. "It did not transmit," was the complaint. I looked at the radio, turned the dial to the normal ski patrol frequency, and transmitted. On frequency. And I could be heard. They did thank me for one of the shortest repair times I had provided.
This kind of a thing happens. Keep it in mind when you are having an after dinner activity with some friends. Relating it then will seem to be much more amusing.
