Leaving the Nest?????

When I first saw this bird's nest it was laying outside of our mechanic's office.  We took mom and dad's Trooper to have some work done before we sold it ($1400 thanks to KSL.com.) The nest was under the hood nestled around and between car parts so tight that the mechanic had to take it out in three or four pieces.

That poor bird mom, thinking she had found a safe place for her eggs, no one had driven the Trooper for weeks, and the next thing she knew her eggs were driving off without her. 

There are quite a few analogies I can think of about that bird's nest and moving mom and dad out of their home, but I don't think I will. You can make your own.
