I think we have misunderstood each other, raficha. To my mind saying one doesn't like curtseys because they are ungainly is chat, not fuss. Other people joining the conversation is also chat, not fuss.
Perhaps where we each draw the line, so to speak, between what counts as chat and what counts as fuss is where we differ. Curtsey fuss to me would be someone making a fuss, which would involve physical actions, about doing a curtsey when in front of the queen, rather than just bowing to her or nodding the head.
If you think talking about something is fuss, we are on a different plane of understanding is all ✌️
