We are almost alone, sitting near the end of the back row of the movie theatre, with the dividing seat-arm raised and you on my left. We got there early, and another couple come in shortly after us, but sit several rows ahead of us. As the adverts end and the previews start, they move to the back row too, but at the other end of the row. We are mildly annoyed at this until they start making out as this is quite a turn-on. A few more couples come in, but it is still a quiet showing, and they all sit several rows ahead of us, so they pay us and the other couple no attention.
When the movie starts, the couple try watch it but, after only ten minutes or so, they are obviously not that interested in what's happening on the screen. They keep looking over at you or us and whispering to one another. After a while of this, she gets up and goes to the restroom, excusing herself past us on the way and pressing against us slightly more than is strictly necessary. I think they are hoping to have the back row to themselves.
When she returns, instead of going past us again, she sits down directly next to me. At the same time her beau has moved to the other side of you. We now sit between them, and he rests his hand on the dividing seat arm, just brushing against your knee. She does the same on my side. We both put our hands in our laps, keeping them from moving any closer. We wanted the back row too, so we are not about to give in and move!
