A short trip to London

I went to London to meet my friend and enjoyed talking and shopping with her (She was so kind).
At first, I planned to go there and return in a day. My host father gave me an advice to stay one night there, because if I go & return in a day by a reasonable price, I could be only 4 hour in London.
Anyway, thanks to his advice, I could spend a good time there with her!
The train to London was not busy at noon, and the return train started at 13:00 also not busy. One of the most surprising things in England is the unstable train fare! It depends on the time, and a morning ticket to London will require double or triple fare of an unbusy time one.

This trip included my first experience to use a subwey alone in London. I heard that many Japanese people often encounter a pick-pocket in the underground.  I was so scared at first, but I didn't use Underground when it was busy, so it was relatively safe.
We walked from King's Cross station to Russel Square to look the way I will use to go to school later.
This way was good because there is a shopping centre, a supermarket, and no dangerous road to walk.
(many tourists were walking)
The next day, we got on the Circle Line and off at Ocford Circus Station. After that, we had a gorgeous lunch in a restraunt in Fortnm & Mason. Following that, we went shopping in Regent street, where are a lot of brand shops. Liberty, a department store, was so cute.
