On the more rational side (ignoring my last post) remember that in some cases it may not be that they don't care, they just may be very uncomfortable with the situation, not know what to say, and so they avoid it. I find that is a lot in human nature, unfortunately, with any illness, moreso with something as little understood (and misunderstood) as depression.

That doesn't help our need for contact though or in thinking why SOMEONE can't break through that and just step up and do the right thing.
