Alternatively, it is possible to be yourself while still caring a great deal about what other people think, but not letting it influence your behaviour. Only your emotions.

I think “not caring what others think” gets too much credit, honestly. It’s fine to care, because that also brings joy, for example I bet your uncle was damn proud that you liked him so much for whom he was :) that only works if you care. Which I’m sure he did.

Allowing yourself to be vulnerable in public is a laudable skill.
