My mother eats "green salads," drinks "sweet milk," and has sandwiches on "loaf bread."
I agree with your mother on the salad bit. Let's face it, if you can call slop made with mayonnaise, potatoes, and/or macaroni "salad," we need the green for clarity.
Who's going to be the one to post "salad" to the suggestion board?
As bread comes in so many forms, I get the idea of "loaf" bread, too.
I'm a bit at a loss over the "sweet" of the milk, though. I have vague, vapid, thoughts thunking away, but I can't quite get there.
Life is like playing chess with chessmen who each have thoughts and feelings and motives of their own.
