Getting annoyed real quick

With this whole stupid Covid.....I feel like in my house it’s taken to a whole new level. Other vulnerable people if they’re worried, yes they barely go out or stay away from others but yet don’t see any harm in whom ever else they live with doing X, Y, Z. I am not completely on my own yet and have to follow Covid rules while living here (for now) and it’s effecting my dating life. So isnt it kinda true tho if someone who lives with a vulnerable person, goes out and gets exposed then goes around a vulnerable person (and possibly has Covid) isn’t it the same thing as if the vulnerable person did X, Y and Z. Many do not see that and I am wondering am I missing something here? Or is something being misunderstood in my house
