history: I had to go to a wedding far out of the city I live in, and needed someone to watch my dogs.  A friend took over last minute and agreed to watch them for the weekend.
current: I was going to a wedding outside of my city, and had arranged to have my dogs watched while I was gone, but the person backed out really soon before I had to leave.
next: Oh no! That's awful!  I watch animals for a few different people and I would never do that.  That's very unprofessional. Did they have an emergency?
