mom’s house, mom’s rules

I'm 24 and I still live at home with my mom. We have been quarantining for several days now, with me working from home and my mom continuing her tutoring job via Skype lessons. Amongst many other things I do that displease her, I like to smoke weed when I'm done working. Out of respect for my mom's home I always go outside the apartment building to smoke my joints. Last night she called me while I was smoking and said that since I had left the house, and since there's no way to know what I've been exposed to, I would not be allowed to come back inside. She said it just wasn't worth the risk, given that she's in the vulnerable age group . So I slept at my neighbor's house and this morning I went home to get my laptop for work. She stayed in her room while I grabbed my stuff. She didn't say anything to me. I think I'll be allowed back home once the virus outbreak has died down, but yeah, I guess for now I'm technically homeless.
