history: I was supposed to go on a work trip but my child go sick. I was so worried to tell my boss that  i wouldn't be able to go. It was an important trip and it was too late for someone to replace me. My child got sick and I had just made arrangements to go out of town on business. 
current: Oh no. How did you handle having two such big priorities come up?
next: I had to tell my boss I couldn't go and I was so stressed about that. It turned out the weather was bad and all flights go canceled so no one could go.
