Input: So my brother often will pick something about me like that I don't really eat meat (for moral and environmental reasons) or that I wear my engineering ring (Canadian engineering thing related to a bridge that collapsed and that engineers need to remember the potential gravity of their actions) and personally attack me for it. In the case of the ring for example calling my wearing it pretentious and that engineers do it because they are elitist pricks basically. And I usually try to explain why because I do these things for a reason and he kinda just talks over me until I stop talking or until he is clearly wrong and then wiggles out of it somehow.

So today we \[my whole family at dinner\] were talking about whether there should be a grade 13 and I said I don't think so since it would be putting a lot of people back a year; my brother's responses were something to the general tone of "you're dumb; shut up". The tone of the conversation was escalating (due to him continuing to talk over me) and then he said something like "...for example I made dumb mistakes my first year out of high school" to which I replied "So since SOME people make dumb mistakes, everyone should be held back a year? That doesn't make sense to me." To which he replied something to the effect of "you can take the bus home" then got up and left the room to do his laundry and immediately the rest of my family started talking to me like I had just murdered an innocent puppy.

I helped clean up after dinner (while my brother was still out of the room) and it was super uncomfortable and I was still being treated very much like a mean villain who was taking revenge so I went to the bathroom and then left silently and texted my family to tell them I was busing home and thanked them for dinner and told them I just didn't really want to deal with the situation right now.

I understand that what I said could have hurt my brother's feelings as he might be insecure about his decisions etc. but I don't think that what I said was a) attacking him directly or b) deserved me being treated like I had just been a total dick by everyone c) merited my brother's response of leaving the room.

&amp;#x200B;

Leaving I think was a bit selfish and cowardly, but I didn't want to deal with the situation and in hindsight I don't think that there was really a better alternative since my family is super dishonest with each other and themselves so at best they would just pretend it didn't happen and act super uncomfortable the remainder of the night and at worst they would continue to treat me like a puppy murderer.
