<human>: I was travelling overseas to visit my family (sister + parents) back home. They planned a small party of sorts for the day after Christmas, and though the children had been sick, they assured me that it had been a week ago. They are aware that I get horribly sick very easily (lupus) and am afraid of catching stomach bugs in particular.

After food had been served, the kids were talking about not feeling good and how they didn't want it to be like last night all over again. I freaked out and asked why they hadn't told me. And not even in an asshole way, in a ''Holy shit I'm freaking out oh god where is the sink so I can wash my hands why didn't you tell me? you know this is like my worst nightmare'' I didn't get any straight answers: instead my sister pulled her passive-aggressive avoidance act, and retreated with my father and her kids to another room and left me (and my newly introduced fiancé + friend) alone in the living room wondering wtf happened while my mom awkwardly tried to pretend everything was fine.

My mom insisted that everyone was staying away to avoid getting me sick. I was told later that taking offense to the kids being sick was ''rude'' and that's why things went down like they did. They said that I was visiting for the first time in years and to make an issue out of something like that was insensitive. Myself, I think I should have had a choice as to whether I wanted to spend my three weeks of vacay sick, and that it was fucked up to alienate my foreign family (who were very, very confused) for some perceived slight instead of talking to me about it.

I'm honestly so upset by this that I haven't phoned home since. It was supposed to be our Christmas together and this kind of petty bullshit ruined it. Was it really rude of me/do I have something to apologize about?

Can you provide a brief overview of the text?
<bot>: family lied about having the plague to get me to come over, got incredibly mad that I got mad, were rude to my guests, bad blood continues
