AITA because I didn't say hi to my brother's wife?

So over the weekend I (23m) went to a funeral of my close friend of 17 years. I needed to drive 11ish hours there and 11 back for the funeral. I got home at around 4 am. I passed out and when I woke up at 10ish I started my laundry and informed my brother (34m) that I put his pants i was using in too and went to my room without saying anything to his wife (29f). An hour or so later he came to my room and was visibly angry and informed me that not saying anything hurt her and that I needed to apologize. When I went to do so his wife was crying. Ever since then I've gotten the cold shoulder from my brother. They say I make them feel unloved unwanted and unseen.
