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. I was going to a wedding outside of my city_comma_ and had arranged to have my dogs watched while I was gone_comma_ but the person backed out really soon before I had to leave.
current: 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?
next: Something like that, they were vague.  It was through a company so I couldn't really get much out of them.  Luckily a friend stepped up and watched them for me.
