Manager talking down because I worked from home

Hello Everyone

I have a strict 3 day office policy. Unfortunately my partner was not well and was running a fever yesterday morning. Therefore, rather than go to office I pinged in the group that I'll be working from home to take care of her.

My manager just sent me a super condescending message today morning asking me why they couldn't take care of themselves and that this is not a genuine reason to work from home.

I'm flabbergasted by their response but would want to understand if they're in the right here. I did explain that my partner was running high fever but honestly it pisses me off that I've to explain the situation in so much detail when I did put in equal hours, just from home.

Would appreciate your perspective on this.
