Quarantine for me but not for thee

I stayed in our basement during my 5 days of COVID. I only went upstairs to use the bathroom and to get food to bring downstairs. 

My daughter's fever is gone at the moment so she's been hanging out in the kitchen and living room with her mask on as though that's a real barrier to being exposed. 

I am pretty sure I can't get it again, so I'm able to move freely around her, but everyone else should probably limit being around her. 

I've a bad feeling everyone is going to get it. Hopefully, I am wrong.
