An text message from my father's friend

Earlier tonight, I received an text massage from my father's friend Mr Choo. He told me that he had been to the Mandai Columbarium to see my father. It was so thoughtful of him. I am overwhelmed by his devotion to my father. I am not sure when they met. I only knew that he was learning Karaoke under my father. So I resume that they only met within the past ten years. And he had always been the one picking my father up post his surgery. When my father was able to walked and ventured out for 1, 2 hours on Sunday. Any longer, and it drains him physically.
In his message to me, he expressed his sorrows of missing him, and asking how are the family. Especially my sister whom he must have realised that my father had been hanging on to see her for the last time. I thanked him and tell him we are all fine. That my sister had been back to see my father during early July and had since gone back to Australia. I told him that I will be travelling to Australia to see her graduated as promised to my father on his deathbed.
Mr Choo replied saying my father would have been most proud that he had us. Proud, I am not too sure. Everyone has their own demons. I have mine too. Especially the days when I am feeling down, flashbacks of my father keep replaying inside my mind. I just wish I had been more vigilant but it is too late now. All I can do is to do what I had promised. This way, I think my father will be in peace. At least my sister is not alone when she is in her full glory and honours. This is something that had always been weighing on my father's mind even when he is undergoing treatments and when death beckons, he always repeat this wish to his doctors. He, too keep mentioning to me and repeating it every single week. So I will be carrying out the promise and perhaps I will find some peace within myself.

An afternote :
My aunt called me a couple of days later, saying Mr Choo had been in contact with her. He had commented to my aunt that my father had taught me well as I was most courteous towards him. I replied saying it was the least I should do for my father at this point. I wanted to preserve his memories as much as I can. And also by respect his friends, I am also respecting my father. My aunt says she was very bothered by the things that my mum and her sister had been saying about my father. She says it pains her and also because of the stuff that they said are not my father at all. I said I know but I have no wish to be drawn into it. I know what my father was like. And everyone who know him well would also know that all these are not true. So it is not important at all. If others would to take my mother's words as the truth, then they don't know my father well. So all the more it wouldn't matter.
