<human>: Hello reddit. I don't want to go into too much detail, but basically our family has been going through a rough patch on and off for a year. Things are bad again just now, and my parents are stressed. I'm old enough that my dad explains to me what is going on and we're honest with each other, but my brother doesn't know as much as I do. 

I know that although things are shit right now, it'll pass eventually. Might take ages, but it will pass. I used to get really upset when I heard my parents argue, but at this point it just isn't a big deal to me. Yeah, it sucks, and it's not nice to hear, but now it just doesn't upset me. 

My brother, on the other hand, is really sensitive. I know that he's worried about our parents. Today, I got home from staying the night somewhere else and within ten minutes our parents started arguing. My brother and I were watching TV and chatting, and they were in the other room. I went up to the toilet and a moment later I heard my brother going to his room. I didn't see him but he sounded upset (that sounds a bit odd but I could tell). 

We used to annoy the shit out of each other, but over the past year I'd say we've became friends. He's my bro and I love him and we can joke around, but I've always been the sort of person that's uncomfortable talking about emotional stuff. Especially with my brother, I don't really know how to handle it. I don't know how to ask him if he's okay without it feeling weird, because we've never done stuff like that for each other. 

So what can I do? Not even just asking how he is, but maybe even how I distract him or something when our parents start yelling. I don't know.

Could you distill the essence of the text into 1-3 sentences?
