It's a pretty big cultural difference between us and Spain as far as bulls and animals in general go. But when you put that aside, the exhilaration and rush of adrenaline you get from fucking around with bulls is unmatched. Just look at their faces after they nearly get gored, giddy with excitement.
The more they run away the easier it is for the bull to connect too, it gives them a more easily achievable attack vector. Running towards them and giving a swift juke will give you a lot better chance at dodging. Most of the boys here look pretty green though, so I won't blame them for not having developed their skills much.
