It is a really interesting situation. There is something about his Culture, I feel, that is causing the Dog problem.
As I read I felt the guy was wanting to be like the dominate one, making you go over to his place ?
When I read you gave him a pocket knife i was worried, "Heck, he's gonna take that as an invitation to fight with knives",... I don't think you can figure this unless you had another equally friendly Egyptian, as it seems like a cultural thing. Maybe Google can help
1.) You subserve to him, by going to his home.
2.) You offer a knife, in his home; which I feel a kind of dynamic; subservience; rather than shove it in his gut (
) you offer the weapon, in peace.
Heck, honestly I have no idea, but if the wife has to walk 100 metres behind, there is a hierarchy involved, on which you may be getting the butt of.
You'd have to ask an Egyptian I think Rudge, I'm really trying hard to imagine what you two guys are up to.
Actually I'll Google Egyptians and dogs; although I've a feeling it has nothing to do with your Dogs, but a "Hierarchal" posturing, ...
