Notright - hello and welcome to Gransnet if you're a new poster.
Your use of the derogatory term 'snowflake' is, I think, rather unfair in the circumstances. I understand that if you don't have ongoing health problems yourself it can be difficult to understand how vulnerable people are when they are living with conditions that make them liable to repeat infections and recurrent illness.
So, to put this into context; I have been severely ill on and off since the end of August last year. I have underlying health conditions that I usually manage well, but every couple of years I get something that overwhelms my immune system. One of my conditions is respiratory and although I am only 66 I fear (I use that word deliberately) that if I did contract Covid-19 I would, at best, become critically ill and at worst I would die. This is not hysteria, panic or hyperbole - just a straightforward assessment of facts based on my medical history.
My family have asked (implored) me to self-isolate and I have agreed to do so, partly because I agree it is simple common sense, but also because they are still dealing with the trauma of my recent illness and I want them not to continue to be anxious about me.
In my shoes (and, I suspect, many others on GN), I wonder what you would do?
