The scene switches randomly from streets to flashbacks n such and I can't really follow it.
You seem to not understand, there isn't anything to follow. It's just a slice of life.
Also I love how some of you are hitting on LS so much :3 It gets pretty funny. You know, a lot of animes have creep material in it. A LOT. But you just chose Lucky Star to criticize.
I love it :D
