It’s obvious you hate Brad and that’s fine, but most of the commenters understand it’s part of a brother/sister relationship. You act like that Luann is never mean to Brad, she calls him a blob, and other names, teases him about Diane and more. I understand you had a poor relationship with your older brother but….
Well, I can attest to it being somewhat true. When we moved in together before we got married my future wife went through my underwear and threw away about 1/3 because they had some holes in them. Later on, when I was doing laundry, I came across quite a few pairs of hers that contained holes, it was a big disagreement then, but she eventually tossed them…..
I am not arguing with you because you are correct, I simply want to point out that Luann can be nasty too.
