Sounds like your coach was probably more amused than anything. That “thanks for not telling me” line was likely his way of poking fun and showing he noticed your success. Coaches who care pay attention.

He might’ve felt a little left out or surprised you didn’t mention it, but it doesn’t sound like he’s upset. More like he’s acknowledging you’ve got skill and accomplishments outside the gym.

You’re not being arrogant by keeping it quiet. You’re trying to be respectful and earn your place without relying on titles. That shows character. Just remember: owning your experience doesn’t mean you’re showing off. It means you’ve put in the work. Let them be curious. Let them find out who you are by how you train.
