my mom went to a door once, and the householder had a goose that tried to attack her, so my mom just grabbed its neck (she didn't know what else to do), and gave her presentation while holding the goose.
another time i went to the door and there was a mirror behind it, and the door had a big window, so you could see inside. i knocked, but nobody answered. i happened to look at the mirror, and saw the guy crawling behind his couch to hide from us. we made eye contact, but he still didn't answer the door.
