Glad to hear you got a bargin. :)
I've gotten a couple of jobs (the legitimate kind, lol) off of Craigslist. Its a great resource. And a lot of decent people use it. Just like anything else in life, you have to be careful.
I heard a statistic once that at every superbowl, there are at least three really, really wacked-out dangerous people in the stands. It's a statistic based on population norms. Yet people still go to the superbowl, rock concerts, school, the supermarket, etc.
The point is, if you take percautions in going about the business of living, you eliminate a lot of the risk and still enjoy living. Your parents sound supportive; they are helping you to be safe and frugal, all at the same time. Hooray! :D
Now go enjoy your fishes! ;)
