I've had this with my father. He was very reluctant to tell people. I explained from a bit of a selfish angle that I would find it difficult trying to explain to people when I needed to disappear from work for a few hours to take him to appointments. Plus other people to help support even if it's just a phone call or text to check how things are going. This is so tough dealing with each day I do feel guilty at times and not sure how the next few weeks months will go. Please keep in touch with any friends whilst your away and if the hospital where he is having surgery have any support for family. 

Thank you I will try but he is Adams no one is to know
