The dog thing got me last night as well. Riding home along the canal towpath, not blatting along at all, just a nice steady ride. Every one of the dog walkers would invariably stand on the opposite side of the path to their dog. The up-until-then unconcerned dog would then stop, look at the owner and decide to join it (or, worse, the owner would call it over) and the stupid mutt would then run right in front of me.
Now I like dogs but I’m sensible enough to give it a clear order and to be on the same side of the path.
Same with walkers, you get a couple walking along and rather than both move to one side, they dither – one goes one way, one the other way to stand on opposite sides. Then you get the case where the wife suddenly decides to join her husband just as husband has exactly the same thought and tries to join his wife – result is that they move straight back into the path! 🙄
Just **** stand still! Stop, stand still, wait for me to pass, carry on. Really not rocket science.
