Is it rude, when I continue eating while you say grace before the meal?
Or is it rude that you expect me to wait and listen when you talk to your god, while I would rather enjoy my food?
Perhaps it matters where we are. In your house we follow your rules, in my house, we follow mine?
But what do we do when we are both not at home? Whose rules do we follow then?
And goodness, what do we do if I worship a different version of your god or no god at all?
Perhaps you pray quietly, and I promise to chew the same way, and we both take it with grace?
