Being misunderstood is annoying, not fatal. The right people will read you correctly eventually.

Being read wrong is uncomfortable partly because so little can be done about it directly. Arguing your case tends to confirm whatever impression already exists, and explaining yourself constantly is exhausting and rarely effective. Time and behavior fix most of it. People who stay near you long enough eventually see the pattern instead of the snapshot.

Choose consistency over clarification for a while. Keep doing what you would do anyway and let the record accumulate. Save real explanation for the two or three people whose opinion actually changes your life.
