The context of the following conversation is Casey's car broke down but her suitcase was inside. She had to carry it very far.:
Casey says I was driving to my parents and my car broke down about a mile from their house..
The friend responds What did you do?.
Casey responds I walked.  Normally this wouldn't have been so bad, except I had my suitcase and it was really heavy..
The friend responds Why didn't you just call your parents to come get you?.
Casey responds I tried but they didn't answer.  It was only about a mile, so it would have been fine if it weren't for my suitcase..
