"Uncle" who pushes his limits too much and too often

I've had the misfortune of coming across exactly the kind of person you're talking about, but in the workplace and at school/university rather than in a family situation. In the past, I have had some problems with family members' ignorance of dyspraxia (especially before I was diagnosed), but being talked down to in the way you describe is something which has happened to me in education (from other students rather than teachers) and at work. It is extremely frustrating to be spoken to as if you're of lesser intelligence when you know you're not, but always remember that it's the people who are doing it who are the less intelligent ones. You could try talking to another family member (eg a parent) about your uncle's behaviour, but it might be difficult for them to approach him about it if he's always got away with behaving like that. Even if they speak to him about it, he may still act like an arsehole towards you (I have experienced this from so-called 'friends' even after I was diagnosed with dyspraxia). The best course of action may well be for you to avoid him, as people like this often end up having a negative impact on your confidence and self-esteem.
