Sometimes the strongest reply to a rumor is a normal week of you doing your thing.

Stories need maintenance. They live on reaction, drama and fresh material, and an ordinary week denies them all three. People form their real opinion from what they watch over time rather than from what they were told once, and nothing contradicts a story faster than its subject carrying on calmly. Doing nothing dramatic is the active choice here.

Keep your routine exactly as it was: same practice, same seat, same work, same people. Be normal with the ones who heard, including whoever passed it on. In a fortnight most of them will have quietly decided it was not accurate.
