Dave has problems. He has a problem with alcohol. He has a problem admitting his ex-girlfriend and best mate are happily married. He has a problem with the way his life in general is turning out. He has a problem admitting that all of it just may be his own fault. And, Dave has anger issues.
In an angry and drunken state, Dave rages in the face of fate, in the face of the forces that determine destiny. The Cosmos responds.
Meikle gets a little deep in this one, touching on quantum physics at times and delving some into New Age beliefs.
Be careful what you wish for.
