Why is it so hard for some people to figure out that not making any decison is making a decison?

I’m not sure what kind of example to bring…..it can run so deep. It can control people’s lives—the kind of people who say “But I didn’t DO anything to deserve this!” — Well, that’s because you didn’t DO anything at all. OK, say an important bill is due and you have to decide where to pull the money from to pay it. But rather than do the head work you keep putting it off, saying “I’ll decide tomorrow,” and tomorrow never comes. In the end, the bill doesn’t get paid and whatever happens, happens, all because a decision was never made. So, in effect, the decision was “I won’t pay this bill,” but people who do that kind of thing never see it that way. Why is that?
