Was Mike Accused of Stealing?

Mike was enjoying cheddar corn grits when the doorbell rang. He looked out the peephole, but saw nothing. "It's probably one of these dumb kids doing their stupid newspaper scam trying to sell me magazines for their football team to get uniforms," he declared. Moments later, the doorbell went off a second time. There was still no one to be seen. He shouts, "Who's there!?" through the door, but there was no response.
Feeling threatened in his own home, Mike decided to be stealthy Anderson by using the back door to sneak attack the invisible bell perpetrator. With a weapon in his pocket, he finally gets eyes on the one thing standing between him and his corn grits. Waiting at the door was...
Just his new neighbor.
Mike tells the story and we are left with many questions: Was Mike being accused? What exactly was in this package? Was it necessary for Mike to take precautionary flanking measures?:
