圣诞节我和我火辣的妹妹
篇一:
姐妹俩的圣诞节
我放学后,一进门就见妹妹坐在沙发上翘着小嘴巴满脸不开心,“妹妹,你怎么了?
”妹妹说:
“下午,圣诞老人来我们学校发礼物了。
可是,圣诞老人没发现我,我没有得到礼物。
”接着向妈妈撒娇,央求买礼物。
记得小时候我也经历过这样的事,那种渴望礼物却又得不到的心情,十分理解,我灵机一动,想出了一个好办法。
“妹妹,圣诞老人给同学什么礼物?
?
”“小雪人!
”妹妹抢着回答道。
“很可爱的小雪人!
”“嗯,今晚是平安夜,你把袜子挂在阳台,然后乖乖睡觉,第二天就能收到圣诞老人的礼物了!
”妹妹一听,信以为真,急不可待地从衣柜里找出一只袜子递给我,示意让我挂在阳台上。
然后乖乖地躺在床上睡觉。
我攥着钱,向商场跑去?
?
路上的行人寥寥无几,路边吹来的寒风使我哆嗦,我真想退缩往回走,算了,不买了。
可脑中又浮现出妹妹那张渴望礼物的眼神,我鼓起勇气,加快脚步又向商场跑去?
?
我拿着买好的小雪人,蹑手蹑脚地走入阳台,小心翼翼地把小雪人放进妹妹的袜子里,才回到床上安心地睡觉。
第二天,没等我睡醒,耳边就传来妹妹的声音:
“姐姐,你看!
我收到圣诞老人的礼物了!
你那个办法真好!
实在太---太---聪明了!
”妹妹奶声奶气地说,说完在我的脸上狠狠地亲了一下。
“哇!
你真的收到圣诞老人的礼物啦!
”妹妹对小雪人爱不释手。
她一会儿把小雪人抱在怀里,一会儿拿出来摸一摸,望着她欣喜若狂的样子,我的心里乐滋滋的。
哈哈,妹妹还真好哄。
无论何地,无论何处,无论何时,我愿自己永远都是妹妹的圣诞老人,希望她永远快乐。
