Remember that time when all the sudden it started really hurting to pee? And you noticed there was a little blood in your urine? And then you remembered that hookup a week earlier, when you didn't have a condom, but you were drunk, and you didn't really do anything that unsafe, but, well, you know? And so you went to the doctor, who told you — thank God — that it was just a random irritation, and you actually didn't have any horrible STDs? But it still scared the shit out of you, and so you stopped — at least for a while — with the random coked-up bathroom sex? And you were really, really careful about condoms?

We remind you of all that just to say: Make sure all your anti-virus stuff is up-to-date and working. A new hard drive costs a lot more than the copay for antibiotics.
