Wait Wait Wait

When I got up, the unlucky things happened in the beginning of day.
We had to take the course "introduction to education" at 8:10 am, My roommate and I got out our room to go to the classroom. When we stood in front of the elevator and waited the elevator, we found that people living on six or five floor took the elevator and overcrowded it in advance while the elevator was up. This situation caused us couldn't go inside the elevator. Thus, there were crowded with people on seven floor just like the interior of the elevator we saw.Because the other elevator under repair. The only thing we could do was wait.
Due to waiting for almost fifteen minutes, none of us had patient. It seemed like fifteen years to us Someone couldn't help but tell the people who live on six floor saved a half space for us, but they still filled in the elevator. At last, we had the elevator to take. As soon as the elevator up through the six floor, we saw that there was nobody in front of the six floor. Why didn't they show sympathy for the other people with waiting for a long time?
