My DS is PDA
He is helpful, caring, reliable. He does chores and looks after our large collection of pets, and he's a fully functioning member of the household. He is autistic and that shows up strongly in his social skills (he's very naive when people are taking the piss out of him for example - he'll get there probably, but he'll not catch up with his peers for a few years. He is developing those skills though)
His demand avoidance is mediated by anxiety, so the more stressed he is, he more he finds the internal demands of his body (eating, drinking, sleeping) frustrate him. He is aware that exercise helps his body and goes for walks everyday to get help keep him regulated. Direct orders are difficult for him and the most successful strategy is that he must be offered a true choice, with no backlash if his choice isn't what you want it to be.
He's adventurous with food, cooks family meals regularly and goes shopping for me. (He'll even remember the things that I want but haven't put on the list and gets the right brands - I've not managed to teach DP this in nearly 20 years). We home educate and he learns best when Intrinsic motivation is the driving force.
The thing is, no one can possibly tell you about this man. It will depend very much on the attitude and knowledge of the adults who have supported him growing up on whether he has the skills to help regulate himself, and insight into relationships. For example, my child isn't manipulative. He is very straight forward, very direct.
I enjoy my son's company, I'd choose to spend time with him - he's funny and often understands situations from a different point of view which I'm finding increasingly perceptive. He's 14 but he's a great kid who also has PDA.
