An unlucky experience

I was walking back to school, while departing from junction 8 after having lunch with my class-mates. Then we walked by the bus interchange benjamin suggested, " why not take the bus to our college, save our walking time" I agree. I tap in to the bus and the balance appear low only left with about 0.80 cents and I didn't has enough cash to top up. I decided for the first time ever to take the cheapskate, just as the train commuters tapped the card and enter the station I followed them at full, entering the barrier without been tracked down by the staffs.
