kunal 's notebook entry: Dec 29, 2010 我不常常去菜市买蔬菜可是昨天跟我的哥哥得去菜市因为我想见面一个人可是只我的哥哥认识他。 那个人的办公室离菜市很近。 我很喜欢跟我的哥哥花时间可是我不喜欢跟他去菜市。我更喜欢去超级市场买蔬菜可是他更喜欢去那个小菜市买蔬菜有 很小的商店。他以为在那儿我们可以找不但鲜菜而且也可以用贱街买蔬菜。是的， 我对他同意可是这不是很耗时的？？ 昨天见面那个人以后我们去菜市。我们停车以后在菜市游荡。他在每个商店停和检查蔬菜。 “ 您好，土豆的价格是多少？”我的哥哥对店主同时举办一个土豆。“10卢比每公斤”店主回答。“这是很贵的。刚才另一个店主说 只7卢比每公斤”我的哥哥说。 然而这是第一个商店在他问土豆的价格。”可是这是最好的土豆“ 店主说。“您想不想卖以这个价格，或者我们去第一个店主。 ” 我的哥哥说。 “好的，好的您打赢， 您可以买土豆以这个价格”店主回答。我的哥哥每个商店做同样的行为。他很擅长讨价还价。那时间我只看我的哥哥和那个店主们的表情。那时我享受得很多。 购物以后回家的时候我请他，每当他去菜市买蔬菜请带我跟他一起。。 你们也应该试试。

kunal 's notebook entry: Dec 29, 2010 I seldom go to market to buy groceries, but yesterday I had to go with my brother to market because I need to go with him to meet one person. Actually only he knew that person. It was first time for me to meet that person. That day he had a plan to go market to by some vegetables and that person lives near by that market, so he gave me one condition. He would go with me only if I would go with him to market to buy vegetables. I like to spend time with my brother, but I hate to go market to buy vegetables with him. I prefer to go super market to buy vegetables, but he likes to buy vegetables from small markets. We call it “Mandi”. Mandi is a kind of small market, where are many small shops. He thinks, in Mandi we can find not only fresh vegetables but also can buy them in very cheap price. We can also find some new vegetables there. Yes, I agree with him but isn’t very time consuming?? Anyway yesterday after met with that person. We went to Mandi. We parked our car and roam in that Mandi. He was stopping at every shop and inspecting vegetables. “Hello, what is the price of potatoes” my brother asked to the shopkeeper while holding one potato in his hand. “Rs 10 per kg” shopkeeper replied. “oh! It is a too expensive, Just now other shopkeeper told me it’s price only Rs 7 per kg” my brother said. However, in real it was the first shop where he asked it’s price. “But this is very good quality, sir “shopkeeper said.” Hey, we want to buy 10 kgs.. Do you want to sell them at this price, or we go to that shopkeeper? “ “ok ,ok , you win . I agree to sell you at this price “shopkeeper replied. So my brother was doing the same things at every shop. He is very good at bargaining. That time I was just looking at the expressions of my brother and those shopkeepers. It was really fun. I was enjoying a lot that time. While coming home, I insisted him to bring me, whenever he would go to market next time. Hey, you should also try it ..
