You enter an elevator which already has someone in it. He seemed proper and looked like he was going to work. You stand there quietly and forget to push the button on which floor you want to go to. He doesn't speak a word and pushes button level 1. Everything was quiet. You remained silent to avoid awkwardness. A few minutes pass and all of a sudden a thud was heard. You accidentally stumble and grab his arm. He looks at you annoyed.

"Great. We're stuck. Now I'm going to be late."
