Kim claimed that Japanese figure skaters have repeatedly disturbed her practice jumps when they have shared ice rink space for pre-competition work-outs. Apparently only Japanese skaters would get in her way, and it really got on her nerves.
Perhaps Japanese skaters have been messing with Kim on purpose.
* Update: Well, commentor Michael has posted this video in the comment section, showing other skaters getting in Kim's way during practice. It's pretty damning evidence. I wonder why her manager hasn't spoken up more loudly about this, and whether judges or officials are also watching warm-ups. You'd think they'd warn and penalize repeat offenders like this. The Penguins signed Georges Laraque to deal with this kind of riff-raff messing around with Sidney Crosby, maybe Kim should consider an enforcer as well.
