You're in a crowded bus, there are no seats left so you have to stand up. Many people push each other and makes you fall to one of the seat. At first you are relieved that you can finally sit, but suddenly you feel a soft palm on your waist. You look behind you and you're surprised when you realize that you're sitting on someone's lap. When you want to stand up again, he pulls you back to sit on his lap.

"Sit here, there's no seat left." He said while wrapping his hands around your waist.
