昨晚陪儿子女儿上完钢琴课，回家的路上是电闪雷鸣。女儿说，老爸，你该高兴了，不用掏钱给草地浇水了。儿子却抬起头，一本正经地说：“Let'scount after we see the lightning until we hear the thunder. The distance from the place of the thunder to us is the number we count multiply by 1000 feet.”

老爸可没有教过这个：“Where did you get this?”

“I read a book a while ago and learned from it. It said that every second the sound goes about 1000 feet.”

学过物理的女儿倒是糊涂了：“Really? I thought the speed of sound is much faster.”

老爸就和女儿开玩笑：“Sounds like you forget everything you learned from your physics class. You brother is correct--about 1000 feet per second.”

儿子马上不放过这种表现自我的机会：“See, I am smart, right, daddy?”

“Of course, you are smart. As long as you work hard, you can do anything in the future.” 老爸嘴里这么说，心里却想着儿子按现在这个速度读下去，八成是个nerd呢。
