Ice hockey is popular in colder places such as Canada and Scandinavia, however it is less often seen in countries as my own such as the United Kingdom. 
I live in the United States and it is very popular here, although I don't know much about it. Have you ever seen a game?
I haven't, no. However, hockey played on grass is common in the United Kingdom and I was part of my secondary school team, competing against other school teams in my county. 
Wow! That's interesting! Is hockey played on grass as much of a contact sport as hockey played on ice?
Definitely not! It always amazes me how many fights ice hockey players seem to get in to. Hockey is non-contact over here, although I have seen the odd person get hit in the face with a stick where the other person has raised their stick too high! 
Ice hockey seems to be quite a violent sport, for sure. Field hockey sounds a little bit more my speed. What position did you play?
Yeah, ice hockey would terrify me! I was always in defense, it's quite satisfying to assist in keeping the other team away from our goalie!
That sounds like it would be a lot of fun! I think I would like to be a goalie! How long is a hockey game? Is it broken down into quarters or halves?
I honestly can't remember, it's been 12 years since I played it now! I would love to get back in to it but I don't know of any local teams unfortunately. It was split in to two halves, and we would swap goal sides in each half to make it fairer - similar to football. Do you know how long an ice hockey game is?
In the NHL, the National Hockey League in the United States, each game is three periods long with each period lasting 20 minutes.  There is an intermission after the first and second periods, but 60 minutes of playing time.
