係呃，重有一樣嘢，就係你買完嗰個袋覺得真係唔鍾意嘅，而家有二手攤嗎，你可以去賣返出去𡃉，好似CD噉樣，你聽完之後，你發覺，「唉！都係唔係咁-咁鍾意成隻碟喎。」噉咪賣返出去囖。
It's a lie, there's one more thing, which you don't like after you buy that bag, and now there's a second-hand stall that you can sell back, like a CD, and you listen to it, and you realize, "Oh, it's still not so—I like the whole plate so much." Then sell it back.
