You’re right we all should be taking it seriously and following the rules but I think what the op meant was that ruby can take things to an extreme, like unless someone is touching your back pack or coughing directly every day you don’t need to sanitise it all the time.
My dad is the same, hes always been a total germophobe but hes also taken covid to a ridiculous level. For example he only goes outside between midnight and 7am, sanitizes any shopping thats bought into the house, demands that the dog gets sanitized after every walk and even went through a phase of wearing an ffp2 mask at all times inside the house, yet he lives in an area of spain which has had consistently the lowest rate of covid since the pandemic started.
Its important to practice good hygiene and protect yourself but you do have to rationalise it to an extent and realise that when you take it to ridiculous levels, its going to effect your mental health.
I think a lot of her covid fear comes from her mum, I read her blog and most of the posts are about how scared she is of covid
