"I think it's about how you should not say mean things to people. Like in our morning message we promise to be nice to each other. You shouldn't say you don't like someone's bed and you shouldn't say their bed is too hard or too soft or just right and fall asleep on it"
"You should be nice to people in the city and in the country, too. You should be nice to people everywhere!!"
"I think the author means you should not try to sleep in places like barns because it might hurt. And you should not sleep in the city where there are too many people and it's noisy. You should sleep in your own bed."
"I think you should be happy.. You shouldn't want to live anywhere else but where you live."
I offered another perspective about how how a peaceful and happy life might be best based on how the City Mouse had to live in fear, paraphrasing, second grade style, Aesop's moral: Better beans and bacon in peace than cakes and ale in fear. But I must admit their ideas are good messages too.
