It is with heavy heart that I got the news of death of your brother. Please accept my blessings and condolences on this sad occasion. I wanted to come on the funeral but I am out of country for some official meeting.
I got shocked when I got the news as I had a telephonic conversation with John before a week. So, it’s really heart breaking news. I will definitely meet you after I come back. In the mean time you can contact me for any type of help.
