Yesterday was Sherman and Dorothy Johnson’s twenty-third anniversary. They went to the Continental Restaurant for dinner. This restaurant is a very special place for Sherman and Dorothy because they went there on their first date twenty-four years ago.
Sherman and Dorothy sat at a quiet, romantic table in the corner. They had two glasses of wine and then they ordered dinner. First Dorothy ordered a bowl of vegetable soup, and Sherman ordered a glass of tomato juice.
For the main course Dorothy ordered baked chicken with rice and Sherman ordered fish with potatoes.
For dessert Dorothy ordered a piece of apple pie and Sherman ordered a bowl of strawberries.
Sherman and Dorothy enjoyed their dinner very much. The soup was delicious and the tomato juice was fresh. The chicken was wonderful and the rice was tasty. The fish was fantastic and the potatoes were excellent. The apple pie was magnificent and the strawberries were out of this world!
Sherman and Dorothy had a wonderful evening at the Continental Restaurant. It was a very special anniversary.
