Once, at a cafeteria, where after each meal hour everyone has to stack their chairs in the back of the room and fold the tables (for whoever was using the place after the meal), our hour was up, so I shouted loudly, "Everyone, it's time to chack our stairs, let's go".
A couple years ago, the place where I lived changed garbage day to Sunday. Whenever I would take out my garbage, I would always check the mail, and I continued to do so, even though it was Sunday and there wouldn't be any mail. Since I'm paranoid, and constantly think that someone is watching me when I'm outside, I said out loud (while checking the mail), "Look, I know it's Sunday, I know there isn't going to be any mail, I'm just checking because I might have missed it on Saturday". I check the mail, it's empty, and I turn around, and there's a guy in the next driveway over just staring at me.
