I woke up lately yesterday because my alarm clock didn't ring. With no time for the breakfast, I rushed out of my house. I had intended to catch the 7:30 subway, and I didn't make it. Have a little time left, I take a taxi instead. I arrived at the school only find, with great sadness mixed with some relief, that the school where should have been full of students was empty. It was Saturday. However, our ill luck showed no sign of coming at an end. When I returned home, I found myself lock out. I had left my key at home. Just my luck.
