Here's an honest to goodness real letter sent to Dear Abby.  How would your answer compare to hers?

Dear Abby: 

I recently bought a small travel trailer that I use for weekend fishing trips.  My dog, Goldie, accompanies me on these short trips and sleeps with me on the only bed in the trailer.
 
My wife, Shirley, is now expecting to go on some of my fishing trips with Goldie and me.  The problem is, Goldie is used to sleeping with me, and I believe she should have first dibs on the bed since she was there first.

When I informed Shirley that she'd be sleeping in the back of the truck, she came unglued!  Now, Shirley and I are hardly speaking.  Goldie is a young Lab pup who is my best friend, constant companion and never nags.  I think my wife is being selfish and inconsiderate, but I'd like your opinion.  Am I out of line? ----
