Sorry, I was being sincere. We had "recess" in elementary school, where we'd go out for 15-30 minutes and play. If you meant the 5 minute breaks between classes I don't remember what we called them, probably breaks. I wondered if you went to some odd high school that had breaks to go play in the fields.
Sure, we had 5 minutes or whatever short breaks between classes. Though I said that I was "busy" during all periods of free time that I had to spend within the school (lunches, free hours, etc.), so I don't think the distinction matters in this case. :)
(For that matter: I didn't really go to "high school", I'm just using that as the name for my school system's equivalent of year 11 to 13.)
