You can’t help it if the music calls you, even if you have no rhythm. At least gramps here has the balls and the energy to get up and get down.
This kid who taped gramps here said he did it to show him how funny he looks when he was dancing, but I think he looks awesome!
Some people will never even attempt the dance floor in fears of people judging their dance style, or lack of, but I find that most people don’t have the best moves.
Just so long as you can keep up with the beat, I think you are doing just fine, and save your judgments for yourself.
