'Aggressive bell ringing'. Can be open to interpretation. Last year I was walking with a non-cycling friend along a shared pedestrian/bike path that was quite narrow, bordered by a canal.
In my view, lots of cyclists riding home rang their bells at a fair distance (from behind us) so that we knew we were there and we could step aside on to the grass, as there was no where much for a cyclist to go to get around us and it was evening rush hour, so there were quite a few bikes. I thought they were being constructive and were mostly very friendly and helpful when trying to pass by.
My friend saw the situation as a load of louts who were taking over the path, ringing bells only to demand we should 'just get out of the way' as they believed they were more important than us and that the bell ringing proved their arrogance.
My fiend got so hostile at being 'bullied' we had to leave the path and go and walk on a main road.
Same moment, wildly different interpretations.
