I remain surprised that anyone minds someone else describing their... misfortune.... as having a fall.
I've had multiple falls and tumbles thoughout my life, many of them caused when running up stairs at school, many more cantering about on mountains. I've fallen off my bike a few times, on icy roads for example, and I've been knocked off it by other vehicles three times. I have fainted or nearly fainted a number of times 'in public' as well, always for a reason such as shock after what minibaggs would call a "nastident".
I simply don't care how anyone else describes these mishaps. It doesn't seem to me to be important. If people want to think me old and doddery as I become so, it won't bother me in the slightest. Why would it? Especially as, in all cases of the mishaps I've experienced, the immediate reaction of anyone has been helpfulness.
If people want to think in patronising terms about me, they're welcome. That's about them, not me.
I'm beginning to think that minding what one thinks someone else is thinking, finding kindness patronising and bothering about the difference between falling and having a fall is about lack of self-confidence - even perhaps a certain physical 'fragility' that one doesn't want to be noticed - more than anything else.
I am less strong than I used to be, slower and less flexible than I used to be, more bothered by the arthritis I've had all my adult life. When it starts to become obvious, I just hope people are patient and as helpful as I've generally found them. They can use whatever expressions they like if they wish to talk about it.
Free speech and freely.
