There is a reason that the ‘girl of your dreams’ is free for Friday night. There is a reason that ‘dream job’ just suddenly came available. There are reasons behind the availability of things to you, especially when they have been previously unavailable, and the sudden opening seeming too good to be true.
There should be no need for paranoia, but take caution in your good fortune. It is possible that girl of your dreams has a habit of turning into a nightmare once established as a committed girlfriend. The dream job may be what you want to do, but the company could have a reputation of overworking and burning out employees that take that positions.
These potential horrors may not be warranted, or may not seem too horrific based on other alternatives. But never discount the misfortune that others may have suffered from the fortune you pick up.
