>>91272085Buy a bulk of cheap creepy looking dolls. Buy one bottle of blood red nail polish number the dolls with the nail polish. Place one in front of their door every time they open the door replace the doll with a larger number doll. Then at night take a black and white photo of the number to times they opened the door print it out. Make sure to print it from a public use printer so you can't be so easily tracked. Shove the paper under their door and write on the back of the photo "I can hear you". Do that sporadically. Maybe the first 2 days in a row but after 1-2 times a week.
