Well my AC blew up on me. You never quite know how stressed out you can be until you quit your job to vacation, have your AC go out, pay out of your "this is my summer vacation money that I've saved up" budget to get it fixed, and then have it render itself completely useless 3 days later.

AC Repair: $145 + tax
AC Replacement: $1005 + tax + installation
World Screwing You: Priceless

What is it they say about silence being golden?
