It's nice to hear from you again. Thamma 's departure day is moved up to 1 Dec because the older thai student has reschedule her flight. it would be better to have trip together. I think he is very lucky to having a good take care from your family. It's very important time for the first year studying abroad. Although he's happy and has good relationship with yours, he changes his mind and wants to get new experience in next year. Thank you for understanding. I truely appreciate your kindness.
