Tom wondered if kitesurfing wasn't really risky.
Brian answered that it was a bit but he added that it had been fantastic. He said that he was actually thinking of joining the kitesurfing club and asked Tom what he thought.
Tom answered that he wouldn't if he had been Brian. He added that Brian had got a black eye, so it was obviously dangerous. Tom said that if Brian asked him, he would advise him to stick to a safer sport.
