Hey Pandas, If You Had To Pick The Most Annoying Thing Your Sibling Does/Has Done, What Would It Be?

I love my little brother SOOO much. We get along better than most siblings, I think. But he is still undoubtedly. definitely. my little brother. And has directly admitted several times to intentionally driving me crazy, of course. 🙄💖 But I have to say that the MOST annoying thing he does is ask me a question and then IMMEDIATELY stop listening or paying attention whatsoever... Then, I'm left talking or explaining something to dead air and feeling like an idiot. (This particular one isn't personal... might just be a thing boys his age do, IDK. But it bothers meeee)
