I HATE TAKING THE BUS TO WORK!!!!! !!!!!!

I was so close to so catching the first bus yesterday morning. I ran as fast as I could but I ended up missing it. I WAITED for a half hour for the next bus. That bus was late. It finally came. It looks like I won't be going into work until after 9am. I just emailed my boss and she said this is the last time I come in late. Take an earlier bus. She warned me saying if I'm late ONE MORE TIME....I'M FIRED. If I'm late again tomorrow I'm going to lose my job. I love my job even though the students don't like me too much. Some are terrified of me because I'm tall and large.
I yelled at the bus driver that I gotta get to work but she said, "Sorry gotta stay on schedual. Not my problem."
