In my opinion, education is all about encouraging children to build positive relationships with other kids and the world as well as helping them learn necessary skills they will find useful when they start their careers. In this respect, I strongly believe that teenagers should spend time with a foreign country or culture and interact with the local people. Needless to say, we cannot turn a blind eye to the financial costs involved, so we have to work on this problem to support children making the most of this opportunity that their schools provide.
