I am raising my eyebrows at Harry’s expressed self-importance here. Like him, I have chosen to live in the other side of the world from the rest of my family. Unlike him, this wasn’t due to any issues within my family. I consider myself close to my mother - we zoom every weekend.
I would never presume to tell anyone that role I play in her life, however, because I am very well aware that when it comes to the day to day support and assistance, I am simply not there. It is others in our family who fill the roles of meeting her needs. They would (quite rightfully!) be rather pissed off if I started sounding off to all and sundry about what I do for her. Telling the world you see yourself as protecting her just makes you sound incredibly self-involved, and dismissive of everyone else who is there for her, Harry.
