I walk my 2 dogs every day, either through the back gate into forest and field, or, if I have to go out in the car we finish up by walking in the very large field between the camping car park and the river (yes, that river 
).
In the summer there are often camping car people, often with dogs and we exchange friendly waves and greetings as we pass. More often in winter we have the place to ourselves but now and again there is somebody like me walking their dog(s) there. All dog people, once again, a bonjour and friendly gesture.
But the other day I saw an ordinary work van parked to one end of the parking so parked at the other end, friendly but polite. Jules on his 33 metre line and Galys on her non-existing one, leaped out of the car and proceded to run around sniffing as is their wont. I soon spotted the man from the van, he was standing still about 50 odd metres away from us with 2 dogs on normal leads, one a Malinoir and the other something smaller. I kept Jules only 10 metres from me, he is not malicious, quite the opposite and that can be his undoing. Quite large and a menacing black and tan in colour, he can be frightening to some dogs as he rushes at speed to say hello.
So I kept to our side of the field and, when abreast of the other group waved my arm in a friendly gesture and shouted bonjour. There was no reply but I understood, the Malinoir was going mad to get at us leaping high in the air as he tried to loosen his owner’s grip. We carried on but then I heard some shouting, at first I thought the man was shouting at the dog but then I saw his angry fist shaking gestures towards me accompanied by what I managed to work out was ‘j’etais la, j’etais la’, or it might have been ‘j’ai ete la’. N’import, same difference ‘I was here, I was here’.
I gathered that he seemed to think he had annexed the whole field by his presence and objected most firmly to mine. Bizarre behaviour. My response was a gallic shrug with arms raised in concert with each syllable ‘quoi alors’. I thought it prudent not to employ my native language’s normal response to insult and the 3 of us ignored the interruption and carried on with our walk towards the river. 
They were gone before we got back.
I wonder of I had tripped and fallen in, do you think he would have rushed to pull me out? 
P’raps not.
