Completely forgot about this story until now. I had a cousin stay over at my house with my parents during a college break. We rented a movie and ordered a pizza, normal everyday stuff. Halfway during the night our neighbors mailbox was blown up by a small bomb. The shell blew all the way to our deck. Cops came to ask us if we'd seen anything. We hadn't and the cops left. We started to get a creepy feeling of being watched the rest of the night. The next morning as we drove my cousin back to her parents house we notice in the snow (which was a few inches) on the barbecue grill cover someone had written hello .
