As an Irish guy... I'm very mad. (Didn't know I couldn't use that word)
As a soccer fan and former player... it doesn't bother me so much. There is no reason for Henry to apologize, as he said, he is not the ref. The ref blew the call.
I took a dive one time out of all my time playing soccer. (About 12 years) It was an indoor game, and I was in the box and got a penalty shot and scored. I don't really regret it, it's part of the game. I actually wish I took more falls so I could have taken more penalty shots. I went 1 for 1 in penalty shots. The coaches son, my co-captain, took atleast 2 falls a game for 3 straight years and probably made 2 of his penalty shots.
I don't really condone cheating in sports... but in soccer it is part of the game and people need to adapt to that.
