I did, I put in my 2 weeks, and my supervisor was really cool about it. I was concerned about disappointing/frustrating her, but she seems as though she's on top of things and was understanding about it, so that was a huge relief.
However, I realize that once you've put in your 2 weeks, its very difficult to put much effort into the job anymore. Pretty shitty on my part, but I know Ive been half-assing things so far...
I appreciate your interest, though, ghost, and I'll keep you all updated about my future.
