I would definitely not recommend a bullfight for children, ages 6 and 10. It can be very messy when the torero fails to kill the bull with a single thrust: sometimes they try to 'work' the bull into turning around until the espada pierces a vital organ; more often the espada is taken out and the torero makes another try. During this time the bull is puking and lowing; and I can see no pleasure in watching an animal die like that
