Travel Alone?

Marieann asked me if I would allow her to travel alone overseas with her school. I said, "Why not?". She told me that school has some Chinese cultural exchange programme during the school holidays and the notice will be given out next week. 
Well, technically she won't be alone as she will be travelling with her classmates and school teachers. :) I will definitely let her go if she is selected because it will be a great learning opportunity for her in many ways - build her confidence, make her more independent, practise her Chinese/ Mandarin, make her appreciate home and us more lol.
