And there is a big difference between people that can and people that can't.

If your significant other reminded you to go to the grocery store, would you get a general idea of what she wanted and go get a bunch of stuff you know y'all need, even if it isn't on the list? Or would you only get the exact things she wrote on the list and nothing else, even though if you applied some initiative you'd realize that she wanted to make pancakes and she forgot to put milk on the list so you go ahead and grab the milk also.

It seems obvious, but you'd be surprised how many people stick exactly to the list and don't take that initiative.
