女人拿起仙人掌仔细的挑选了很久,价格不贵,与花鸟市场上的相比便宜许多,便挑定了自己喜欢的两盆,准备一起买。

②老头儿布衣布褂,黑褐色的脸上堆满了笑容。

他操着极生硬的普通话,如数家珍般介绍这植物的种种优点,什么如何好看好养了,什么净化空气了。

末了他搓着厚皮疙瘩的手爽快地说:“你要两个,那就算你小批发好了,再便宜你一块钱,你看咋样?”③“你这是真嫁接上去的口还是用牙qiān插上去的?”这样的价钱,女人总觉心里不安,指着山峰顶部的红黄绿颜色的仙人球满脸怀疑地问。

蛮好的花买回家后发现居然是新种没根的,这种事情不止一次了。

老头儿的脸腾地红上来,紧锁眉头,瞪着浑浊的眼睛说:“怎么可能是插上去的?怎么可能呢?这可都是我一棵一棵亲手栽起来的啊!”老头儿本不地道的普通话,这时更是结结巴巴地有点南腔北调了。

④“是吗?”她抬起眼皮,瞟了他一眼,反问道。

这样的看似暴怒的伪装她也见多了。

倘若是货真价实的东西,何必这么着急,她心里想着,不再吭声。

眼看就要成功的交易,因为这一问停了下来,空气似乎也凝固了。

老头儿的脸涨得更红了,忙不迭地解释。

而他越是叽里咕噜地絮絮不止,她就越觉得他不可信。

⑤忽然,老头儿停了下来,从筐里拿起一棵茁壮的仙人掌,没等女人反应锅炉,使劲一拉,把它的顶部从底峰上扯了下来,然后一手一半举到女人眼前:“你看,你看!有牙签吗?”他用力地问她,眼里似乎也冒了火。
