It's not about pride, it's the fact that dog food is just that, dog food. It lacks the substances you find in proper human food. And plus, have you ever tasted dog food before?
It is food manufactured for dogs, it may not have all the nutrients in the proportions ideal for humans. My great grandmother told of several winters she survived on bark soup. I have no doubt that she would have gratefully accepted dog food if someone had offered it to her. She'd also have grown to over 4 foot tall, which she never did as was.
And plus, have you ever tasted dog food before?
If you read my post in it's entirety, you'd know I'd smelled dog food being prepared and thought it smelled delicious after only a 7 hour fast. Give me 24 hours without food and a couple of spices, and I would feast on it.
Of course it's about John Munyes pride. He's not starving. He's probably not missing any meals. IMHO he'd probably feed a family of twelve for two weeks by himself.
And what "substances" would those be? If I was starving I doubt I would be too worried about "substances" that might be lacking in the food. I would be glad there were "substances" that could keep me alive.
Also, it has happened that men have eaten dog food by mistake thinking it was meat spread and thinking it tasty at the same time. Several ladies have told stories of hubby accidently eating the leftover dog food they put in the fridge for the next day.
