I get that, thus why I recommend asking them questions: They might refuse, of course, but it's usually easier to talk to someone if you're the one engaging them.
Basically just care more. If you ask how they're doing, go beyond their answer: Ask why that's the case, ask what's new that's causing it to be good. If you truly want to bond, engage them and don't let them shy away. Remember you probably do the same thing, so it's best you try to undo that for others.
