Ah, an AskReddit that I can answer.

My brother is three years older than I am. He was diagnosed when he was young with autism. He's high-functioning, but his autism is mild-severe.

Greatest effect: My brother cares about everyone in my family, including my close friends. He's very good at video games, so whenever I play Kingdom Hearts he'll come in and watch me play and give me tips. Also, he loves going to my baseball games, track meets, and assorted sporting events and supporting me by bringing me Gatorade or some food.

Worst Effect: My brother gets very obsessive. He will bug my dad about some new power tool that he should get, or he will spend nights watching videos of video game trailers and gameplay videos. There are plenty of nights where he doesn't get sleep because of it. One of the worst effects he has had on my life happened when he was younger. He was really restless in class and acted out by hitting another student with his shoe, and then, when the teacher yelled at him, the teacher as well. Well, the teacher called the police and my brother got suspended (and ultimately expelled, if I remember correctly). My parents were upset with how the district handled the situation, and we moved to another school district about 25 minutes away, which meant I had to leave all my friends behind and start a new life in middle school with people I didn't know.

Do I get mad at my brother? Sure. We all do. One of the hardest things for me growing up was understanding why I got such severe punishments for little things when he would hit people and receive such little punishment. We live such different lives, though, that it's hard for me to talk to him.

If anyone has any more questions for me or for him, feel free to ask them. There are plenty of stories, too.
