五十便士一堂课

车子的一个轮胎没气了，我去了不同的三家加油站充气，甚至半夜下班回家的路上，结果还是没用。于是，我去了第四家。这次，在我用气泵之前，我检查了一下气泵。哦----，明白了，原来需要塞进五十便士硬币，气泵才会工作，我还以为免费呢。

五十便士一堂课，十分有用----世上没有免费的东西。

A Fifty Pence Lesson

There was a tyre of my car, the air pressure was lower, I went three different petrol stations to use the air pump to increase, even I did on the middle night when I was on the way home after work, but the tyre changed nothing.

I worried then went to a petrol station again by the fourth time, I checked the air pump before using, Ohhh, my God, the pump needs feed a fifty pence then start to work. I thought is free.

I got a very useful fifty pence lesson----nothing is free in the world.
