My brother thinks I'm annoying

My brother always tells me to shut up if I've just constantly been talking. I guess it's pretty annoying because it's not necessarily clever or funny all the time, but I talk because I'm bored. I'm really working on reading social cues better and listening to people so I can talk to them instead of at them, but even still I make a lot of noise and go on and on to keep myself entertained. He'll always act like I'm being super cringe. I'm trying to be better, but I have no idea what's wrong with me. Am I just being awkward? How can I work on it?
