...milk? Why would milk be in a pool? A sniff of the air tells you it's not curdled. You kneel down to drag your finger in the warm white substance. It's soft and smooth. It reminds you of the warm milk your mother used to make when you couldn't sleep at night.
You suddenly realize that you're thirsty. You left your water bottle at home and the long walk has you parched and even a little hungry. The milk looks good enough to drink, and it obviously hasn't expired.
As you cup your hands to drink it, you wonder who could have filled it, and why. It's obvious the house isn't abandoned, and milk doesn't stay very long at this heat. It must only have been hours, if that.
You bring your hands up to your lips. The warm milk goes down your throat quickly. It's simply delicious. You can't remember the last time you tasted milk this sweet and smooth. A strange feeling washes over you, and you suddenly have an idea.
