London, Here I Come

I am supposed to go to London in couple of days . But the thing is I donno who i am going to meet or what iam going to do there. New place and new people (as if i knew everybody here). It's like reading a zillion page novel and the best thing are u donno whats gonna happen next and whether the novel is a comedy/feel good/adventure/tragedy( doing my best to avoid the last genre).
