Dear Katrine,

I realize now that in September 2020, your sister’s boyfriend probably wasn’t invited to your house because your region was in complete lockdown, so he couldn’t even visit since he lived 2 hour drive away. She was panicking about that – that he would leave her because they can’t see each other. And then she was additionally triggered when she wanted to invite some people to your house, and you tried to limit it because you were sick. And that’s when she had that tantrum…. Is that what happened?

I hope I got the rest of the events right.
