If I act as if I have it, then I don't make my mother's tea (and she doesn't make mine) and I don't give her a hug and a kiss goodnight. I don't think it's worth giving that up just to reduce the chance of catching coronavirus from 0.2% to 0.19%. Each to his own.
If I have coronavirus, I will change my domestic arrangements. but if I have no reason to suspect I have it, then the potential gain is not worth it.
If you have it then by the time you change your behaviours it will probably be too late, far better to act on the side of caution, would you ever forgive yourself if you gave your mother covid? I hope she has had the vaccine by now though and at least with one dose you are putting her and yourself at far less risk.
