person A: Someone knocked on my door the other day. I peaked around the corner so they could not see me. 
person B: Oh boy_comma_ was it someone you didn't want to talk to?
person A:  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.
person B: You can never be too careful! I've heard too many things in the news. Who did it end up being?
person A: I don't know. I never answered it but it was a man and not in anykind of work uniform.
