He's natural side is very spiteful. At least Dexter takes banter, Sam got offended at Gina's fashion tips she gave him. He's arrogant and hides his crap personal traits by sleeping all day. Sam wouldn't be a likable guy outside the house. Seems spoilt and defensive and has nothing to do with his hearing aid. Many people with disabilities work on their personality to get by, he clearly thinks he's too good looking.
