rollers accident

Just had my first training roller accident have watched and laughed at you tube footage i had my own inccident tonight.
i was about half an hour into an hour session with my 5 year old daughter watching at which point she walked forward and reached for my front wheel. I grabbed both brakes instantly stopping then lurched side ways still clipped in i crashed into the garage floor and my roller tool box, 5 year old running out to tell her mum. while i try to get up 2 holes in my shin just below the knee a large cut to my right butt cheek from the roller tool box draw and now some impressive swelling of the shin.

my daughter is now covinced i felt on my own and she was going back into the house.

anyone else had any incidents on rollers ????
