Dear Maneechan san,
You are excellent leader in my team. When you are working with me, I am very happy. It's make me can fly for business. Please remember good thing in TIT only. I know well, TIT will lose important key person in my team that is make me feel terrible, disheartened and low power. However, I hope you have good new work with better company. Please take care of yourself. Good luck my sister.
Thank you very much for everything for me and TIT.
