I'd ask my good looking companion - "what world are we on again?"
That actually would be pretty cool, i would like that
I'd quickly run into my house, in case it's poisonous or something.
IT'S NOT SNOW IT'S ASH!!!!!!!!!!!
(you have no idea how long I've waited to be able to say that...)
I'll look at it for like a minute then shrug it off.
I don't ever get to see snow and I never have... except in pictures or on tv. So even if it was blue or purple, I'd consider it some type of miracle.
I'm not sure how I would react, but I will say this: It would certainly be a strange, but interesting experience! :)
I would go inside and drink hot cocoa with black marshmallows. X)
I would wonder what was going on.
