Why it's rude to eat in newspaper to read?

Yes, the objection is justified if we sit with someone at the table, the food should also serve the communication. Newspaper can be read still, if the meal is finished. Or take your free time per day less than a quarter of an hour? Not only do you not worthy of your comparison, I also sometimes assume that your mother has previously cooked food. It would be polite to eat this food then with pleasure and not to hide behind the newspaper.

Basically, I would say it is ok for breakfast. Finally, the newspaper if you have already subscribed to it, and then still worth something one wants to start the day informed. At lunch there is something odd, then read the newspaper then. Actually looks more like escape. This may be understandable with your mother, but polite is absolutely not.

your mother is quite right. When you are together then you want that you do together what (if only it is eating well) and if you read newspaper then they may have the feeling that you are not worthy and rather do what you want to eat alone than with her. If you are invited by a girlfriend to be good then you would find it when they talk while listening to you but only with one ear because she reads a book? If you complete the polite thing is to eat the simple !

I also like to read while eating. That's why I'm always happy when I after work sitting alone at the table, because the family has already eaten. Read the newspaper, I can relax at best. Rude, it is probably because you do not correct his opponent perceives and just interested in other things and not for his opponent, even if you are involved in the conversation, it comes over the speaker for a half-hearted and disinterested. You have to eat together, or you have the option to withdraw yourself into your room? Or linger at the table and sit on a newspaper without reading?
