It was a cloudy afternoon in San Francisco. An Italian butcher sold a pound of liver to a very old woman. He didn’t want to sell such a large amount of liver to her, so he had recommended her another choice, but she insisted.
He imagined that she had five hundred bees waiting for her and the meat. The thought made him sick.
She bought a pound of liver and went back to her home on the top of a steep hill. The door of her house was a dear and trusted friend of hers. She opened the door and nodded at it. What were waiting for her in her house were a large number of bees. Bees were everywhere in a room. Then she gave the liver to them. It would be a sunny day in San Francisco.

最後の"The bees came to her and gathered ....that soon changed into a sunny day."　というのが、よくわかりませんでした。
どうして、曇った皿が晴れた日に変わるのか？　

以下middle-angelさんのレス
不透明な（cloudy、つまり曇った）お皿がレバーを置くことによって赤褐色（liver、つまりsunny）に変わることを表現しているのでは？
だから彼女は肉屋のおじさんが「雨になるよ」っていうのに対し、「いいお天気になる」と言っていたのでは？
あともう一つ、golden beesがお肉にたかっている様をsunnyって表現しているのかも・・・とも考えますが。

An Italian butcher was to sell a pound of meat to a very old woman. The butcher advised her she buy some lean hamburger meat. But she didn't like what the butcher recommended. She wanted and insisted a pound of liver. Nevertheless the butcher told her he would have hamburger the weather like raining or going to be rain. The butcher felt unpleasant and didn't want to talk to her anymore. He sold a pound of liver to her in disgust. He went back to the poultry section for a change. On the way back to home, she had to climb up the steep hill. It was so hard for such an old lady like her. Her house was on the top of the hill. There was her dear friend when she opened the door. She walked down the hall to the room where she had a lot of bees. The bees were everywhere in the room. She unwrapped the liver on the silver plate. The cloudy plate soon turned into a shiny plate.

韓国の方が雨の日にチヂミを食べるように天気の悪い日にはハンバーガーを食べるのかしら？お皿は蜂がレバーを食べてきれいになって光ったのかなと一瞬思いましたが蜂は食べるのではなくて吸うのですよね。Middle angleさんの書いていらっしゃるように蜂が集ってsunnyに見えるのではと思いました。
