A bit of a light-hearted story to interrupt the usual bickering here... My car was parked in the street in front of my neighbor's house so I decided to summon it the 35 feet or so to my house, which I did, no issue. A few minutes later I noticed that the dog would not come back into the house. She just sat there staring at the car, waiting for the driver to get out. Because that is what ALWAYS happens when my car pulls up to the front of the house. After about 15 minutes I had no choice but to go out to the car, open the door, get in and get back out.
With order now restored to her universe, she followed me into the front door. (It sort of defeated the time-saving purpose of using summon, however.)
