a tiny money matter

Seems kind of silly to call one a credit card and the other a debit when they both reduce the amount of money you have. It's nice to have two different names for them though.

I was looking at the word "debit" and realized how extremely close in spelling it is to "debt." And then I realized that the reason my debt grows is because "i" spend money! Interesting, isn't it?! Well, maybe you've already thought about that stuff, but it was new to me.
