Technically it is not mine but one of my classmates. As you know high students are forbidden to bring phones unless he hands it to teacher and can fetch it back when going home. One day one of my classmates had a sudden urge to order a takeout food so he sneaked into the teacher's office and got his phone. Unluckily, he met the teacher when back, and out of great nerves he dropped his phone carelessly! Finally the teacher ordered food for him.
