Let me tell you all a ghost story.
I was at the Changi Hospital one day. Visiting a relative. It was already late at night and I was intending to catch the last bus home. When I was on my way out, I realised the place was pretty empty except for an old man. It was pretty creepy. When I was about to walk out the old man came up to me and told me not to take a bus back and asked me to take take a cab home instead. I believe he was trying to tell me something about some ghost or whatsoever. I don't believe in such things. So then I asked him why. He said if its a single deck bus then it's alright to take, but if it's a double decked bus, do not ever take it. Since he failed to answer my question, I asked why again, and this is what he said, "Because ah, when you take the single decker bus you can see the driver. But when you take the double decker bus ah, when you go upstairs, there's no driver!"
The story above was made up.
Go and study. Will be on a hiatus for awhile.
ps. I'm feeling nervous
