Just interested really. When I was a child we had a dog and he was allowed everywhere except while we were eating. My mother had a very negative image of having an animal in the room (usually kitchen) while we were sitting down to dinner as the dog would clearly be interested in the human nosh (people feeding a dog scraps from the table would be enough to turn her stomach). So, for the duration of the meal he was locked out.
All these years later and I have to admit I'm every bit the same as my mother. I've got a cat and she's a real charmer, but moment dinner is ready she's on the other side of a locked door so we can eat in peace.
YABU - don't look animals out
