Weekend's London

I went to London yesterday. As usual, some roads a are blocked and some are partially blocked. I am wondering, does this happens to London every weekend or just for special occasions only as Christmas is coming.

This is a real busy city. I realized this long ago but yesterday I experienced it myself. I was standing in front a shop waiting for my friends. Groups of people walked past me non-stop. People tend to look at me in a strange way, it was like 'why this guy is standing here' kind of look.

Although I have been to London several times, I still cannot remember the directions well. Next time I need to recognize the places instead of scanning for girls.
