What's the difference between an auto mechanic and a quantum mechanic?

Another shadow pic. Just because. It reminds me of the early morning which I love so dearly. There is no better time of day for me. And the extended shadow reminds me of infinity.
Question: What's the difference between an auto mechanic and a quantum mechanic?
The quantum mechanic can get the car inside the garage without opening the door.
The cats chose to stay out last night but they certainly seemed anxious to get in to the food this morning. It's the sound of the can opening that gets them front and center.
Which reminds me of the Sound of Music. Which reminds me of 76 Trombones which doesn't remind me of anything at all but the music. They don't make 'em like that anymore.
Music from Broadway shows is proof that were all on this flight together.
