i had an exchange student on a special condition. she was a girl...my school does a ton of stuff with both year round and just part time stays. my deal was that 20 french kids came here for halloween for 2 weeks, and in april we went there for 2 weeks. it was awesome. generally if they're your age, and just an easy person to get along with, and open to try new things, you'll be fine. oh, and if hes good at english, or ur good at spanish lol. if not there might be a few problems
