While watching TV, you fall asleep on your couch. When you wake up, you're in a tiny, cramped box with absolutely no light and not a sound. WWYDD?

Probably instinctively break out of the box and find out what's going on. Or if my mind works faster than usual, I'd poke a teeny tiny hole in the box if it's poke-able and try peek at what is outside and then pray and figure out what to do.

You are reading a good book on a free, sunny afternoon, but you're thirsty for water. You could go up and get a drink of water, but you're just two chapters away from the ending so you read it. 15 minutes later after you've finished the book, you go to the kitchen to get some water,(if you don't normally use solely tap water, let's hypothetically assume that you do. All the bottles are empty), but before you can pour yourself some, a large siren sound comes on from outside saying that due to a sudden water shortage in your town, all water sources will be dry and the taps, hoses, etc. will not work for an unknown time period. Just two seconds after that announcement, another announcement sounds that says that water bottles have been sold out at all the grocery stores in your proximity. WWYDD?

Drink lemonade instead!

You sketch a landscape of a place in your imagination, then look up and realize you're right in the middle of it! WWYDD?
