Coincidents?

So last night we had one of our very irregular proby tests for new firefighters. Tammy was taking the test and I left work to be there. So what happens when things are about to start? We get a call from the Red Cross that someone's house has burned down and we need to go and do the Red Cross thing and help them. Since we are also Red Cross volunteers.

I went and Tammy stayed to take her test. We have only had three other calls and both times me and Tammy could not go together. I really wonder about these calls and whether we are really supposed to be doing this.
