One of those duh moments...
I'm sitting here working on my homework. I had to re-download a document that I thought I was done with because I needed one piece of information off of it. So I download it, use it, then put it in the recycle bin. Mind you, I've never actually printed this document out, it's just been on my PC. And then I think, wow, I'm wasteful, getting rid of documents that I still need instead of hanging on to them. That's horrid. And then I smack myself on the forehead because I'm being dumb.
