Listen, if you're intimidated by someone else's level of skill, and if that annoys you, or makes you think that they are showing off...

That's your ego speaking.

That's your ego assuming that everything is a competition and a challenge.

When someone has a high level of skill, observe & learn from them.

And when someone sees your level of skill and they ask you how you got there, you can help them! Give them your best advice. You might change their life.
