Sam as I always call you,you were more than a work colleague to me,you were a brother, we shared so many thoughts,advises,pain and worries together. I remember my first shadow shift with you, you took me like a brother and told me what I needed to know on the job. I wish you never left us this soon,but who am I to question God. Rest on brotherly, and may the good Lord comfort your dad,siblings,your loving madam( as you always call her) and us your colleagues. I and Dai will definitely miss you.
