Last night, Mack got a flat tire on the way home from work. His spare was flat too so he had to wait on a friend to come help. When he got home, he realized that he didn’t have his house keys so he was locked out. His cellphone was dead and he couldn’t call for help. He drove to his mother’s house to wait on his son to get home with the keys and charge his phone. He fell asleep at his mother’s house and didn’t set an alarm. He did not wake up until 10 am the next morning. He was supposed to be at work by 9:15 am. What should Mack do now?
