Someone knocked on my door the other day. I peaked around the corner so they could not see me. 
Oh boy, was it someone you didn't want to talk to?
 I don't know anyone and was alone so I wasn't sure if I should answer the door. Things are getting pretty scary in the world.
You can never be too careful! I've heard too many things in the news. Who did it end up being?
I don't know. I never answered it but it was a man and not in anykind of work uniform.
