Person in this vehicle banged on my house door with a purpose. Upon answering, I was asked if I lived at 1400 while I live at 1401 North Reid St. The person did not give a reason for being so aggressive, which was very frightening, as he just walked away, leaving his truck parked in front of my home. I asked him to please move his truck as it was blocking my mailbox. However, while sitting on my porch waiting, he returned from 1400 North Reid across from me, gave me the middle finger, and went on his way.
