She smiled and sarcastically said "Hi there, nice weather we're having, huh?" I chuckled a bit and smile held out my right hand and said "oh just wonderful, My name's Andrew." I started to think she thinks I'm crazy or something but there's no harm in being friendly and honestly she wouldn't be the first to think so and she probably won't be the last. Anyway it's good to do this to show people that even though a majority of the population has been wiped out there are good things, and to cool peoples nerves.
