I have a fren from work who has problems. He went to a behaviour and learning disability school. I went out with him last night and he only had 3 pints. Hes always on edge, very angry and hateful of everybody. He has absolutely no hobbies and never listens to anyone when you're trying to offer him advise. Hes clearly not very intelligent and he has absolutely no aspirations when he's 29 years old. He just rages at everyone behind their backs and bowls around thinking hes hard. He cant concentrate on anything and has no desire to learn new things. Hes also very cocky, especially with alcohol. He acts like a delinquent 16 year old school kid. A lot of people dont like him and I can see why, but i thought I'd give him a chance. I think he may have ADHD. What do you think?
