For those who can’t read:
This girl with a humanitarian mindset:

I sit on the last row of seats in the trolleybus, in the corner, I also pulled my knee to myself, in general, I sit very compactly, facing the back seat, and I talk on the phone with the boss. Suddenly, the trolleybus falls and the horns and it stops very sharply, people fall. And I see a huge (really huge, 150 kg) ass fast approaching me, closing the horizon. It’s getting dark, and nothing but the ass around.

Read on Yandex about inertia. Sitting in the last row, with braking, in the worst case, you could head that ass instead of serving as a landing ground for it.

The words "face to backdrop" do not point to the thought, or is the reader not a chukcha?
