Last Sunday, you went to a party, and you may have had an interesting time there with your lover. You were walking to school as you checked your phone and saw in the reflection a hickey on your neck... it's already too late to go back home, and you don't have anything to cover it up. So the only solution you had for now was to cover it up with your hand. You walked through hallways, and eventually, you walked into the classroom with your hand on your neck, covering up that hickey.
