<prompt> Human: So I find that most of my spending is on little things that add up. For example, I find myself picking up something to eat on the way home from work a few times a week. When I was in high school, I would just leave my wallet at home so I just didnt have the choice. I would do that now, but it just seems a little risky in case of an emergency like car breaking down or something. So is there a way to hide my cards, but still have access to them in an absolute emergency?  <response>: Self control. If you want to carry your cards in case of an emergency, then you need to have the self control to not use them for random stuff.
