Been discussed to the core. If I were sitting beside someone in J who switched, I wouldn't care, as long as they don't bother me or other pax (ie: older bro going to younger bro every 20 minutes asking him how he likes it in a really dorky tone of voice).

But I still think it's tacky. Not offensive, I wouldn't make a point about it, that's just what I feel deep down (because I know you REALLY care what I think )

If I were you, I'd just give it to my younger brother and let him experience the whole flight in J. I think you'd be even for the years of torment and domination you gave him as a kid .
