For you, it's just another Friday. You got home from work, loosened your clothing, and plopped onto your couch. The remote flicks the TV, and you relax, ready to doze off any minute.

It's raining outside, the pitter-patter of the rain tapping against your window. It's bothering you. You turn the TV up higher, but the tapping continues. And so, you walk over to the window to see the noise. Is that a foot...? You scan the window, and see a face staring at you. The man mouths: "Let me in, please."
