Communication is a skill most of us practice every day.
Often without realising we're doing it.
I take my communication skills for granted. I'm not a brilliant communicator, not the best by any means, but probably, yes, I'm a bit above average. It wasn't until a colleague remarked on my presentation skills in particular that I remembered I'd actually been taught a thing or two about being on a stage. First as a dancer, then as a performer, and finally as a theatre director.
