I've actually not really spent much time with him. They don't live near us and I moved away before they were married.
But he's not of the "jerk" variety... just sort of socially awkward and has difficulty understanding certain things and situations like he just can't process it "normally". His parents are also not of the "involved" variety so it may have been evident in him as a child but it's entirely possible they just didn't care or didn't notice or thought he was just a pain.
