I like how you take a very small thing that's bothering no one in the world and you analyze it like it's your homework 😆 and you make it informative too! Ever thought about making a youtube channel?
Btw if you tell someone in Arabic "you're loyal like a dog" I'm pretty sure it'd usually be received as sarcasm, although it depends on how nice and optimistic the person is, but most people (from my experience) are sensitive to negative words regardless of context and would easily misunderstand your intentions.
For example, here in Saudi Arabia it's very awkward to bring up a guy's mother, even if you're only asking how she's doing after surgery, of course a lot of people are more loosen up today, but this is still something you consider carefully in a conversation.
True, depends on how you say it.
As for the Mom things, people are more "cultured" here these days, if you're a decent person you won't have to be careful about saying the word "Mom" in a perfectly normal context.
On thinking about it, it's not a common issue here, but sadly there are still ignorant people who view their women as something to be ashamed of.
