Dave's self-absorbed personality, biting sarcasm, and his general lack of the ability to care about anything except himself is hidden by a kind "caring" persona. Of course, this doesn't mean that he doesn't care for people, but he could definitely care more. Though he can always draw people in with his great storytelling skills. Dave doesn't feel close with people easily, but that doesn't make his ant less of a social butterfly - just maybe not the type you'd always like to talk to..
