In your school when it's lunch time, you need to stand in a line to get the food

Today it was as usual, but at some point you zoned out and didn't notice the line moving forward

Since you were just standing there, the line already away from you, a girl behind you held your waist and leaned it in to whisper to you

"You know that the line has moved already, right?"

She started moving you forward to the line, still holding your waist
