My dad gets up in the morning first. I get up at last. Why did not she eats porridge for breakfast? Yesterday we had a very tasty lunch. at first we had the mushroom soup and the second fish and fried potatoes. Drink a glass of juice. What we have for breakfast today? I'm hungry. How about a snack? We no longer have lunch mushrooms. We were just going to dinner. I do not like cocoa. I just can not stand him. Do you love mushrooms with sour cream? Or would you prefer honey? My dad loves sausages with sauerkraut for dinner. Some people like to eat porridge for breakfast.
