The Metro train waits for no person. When one in our party with mobility problems entered slowly, I was doomed to be crushed by the vice-like grip of the Metro's doors. But at the last second Dasha (in blue shirt), our interpreter, intervened and propped the doors open with her elbows as I dragged my camera gear inside. The next day she had a bruise on her arm in a design matching the Metro's rubber door seals.
