London, the third densely populated city of the world... I was here on the 2nd visit, along with the Singaporean Malaysian Society. The main thing I learn out of this trip is the underground interconnection... a bit complicated at first, but now I think I wont get lost next time when I am to use the Tube. This trip I managed to catch a glimpse on the guard change near the parliment house which happens everyday at 11 am. Reached hostel at about 10 pm...
