The horror!!!!

Tonight Riley came running into the TV room, "Mom! There's some creepy animal in my window well! Come listen!" So I ran in there and we listened and sure enough after a minute I heard a distinct and loud chittering/chirpy sound. It was obviously coming right from the other side of the glass. So we ran upstairs and made Matt come down to listen. Sure enough he heard it too. He thought it was probably a bird or something, but I was imagining all sorts of crazy woodland creatures, opossums, raccoons, etc. and in my imagination they were just waiting to leap at my face!
We decided to get flashlights and sneak up on it from outside, because of course that would be more dramatic and more scary. So all three of us crept around the side of the house and quickly shined our lights down into the window well!! AAAAUGH!
It was a giant snail... It was slowly sliming it's way down the window and as it crept, it's shell would rub on the glass making a strange chirping noise.
So if you ever want to scare someone, just stick a big snail on a rain soaked window late at night. It's terrifying!
